Description: Detailed large map of Michigan State, USA showing cities, towns, county formations, roads highway, US highways and State routes.
This map of Michigan with cities, counties, and roads is already large enough to read directly on your desktop. To see a full-screen zoom view on a phone or tablet, tap the map image (or tap the Zoom Map label above the image). Scan by shading by county first, meaning the 83 counties are in various colored blocks with each county's seat in bold. Use the interstate system and Lake Michigan, Lake Huron, and Lake Superior for quick orientation. Note that the light road layer is intentionally minimal and not designed for turn-by-turn directions using interstate (I-75, I-94, I-96). If you want a specific city or county, the full county and seat index and FAQ's lower on this page are the quickest route to click straight to it.
Map of Michigan (USA). Michigan map with cities, counties, and towns. Use this detailed map to understand Michigan's full county grid, every administrative capital (county seat), the major cities and towns, bordering states and waters, and a few highway cues for orientation only. It is the best map style for residents, travelers, and geography students who want clarity without road clutter. Michigan is unique among the states because two peninsulas, not one, hold its 83 counties, and the shape gives it away the moment you look at the map: the Lower Peninsula is the familiar mitten, bounded by Lake Michigan on the west and Lake Huron on the east, while the Upper Peninsula, often just called the U.P., sits above it, wedged between Lake Superior to the north and Lake Michigan to the south. The narrow Straits of Mackinac, spanned by the Mackinac Bridge between Mackinaw City and St. Ignace, is the only physical link between the two, so follow the map out from that bridge and the rest of the state's layout starts to make sense around it.
Borders and waters at a glance: Michigan borders Wisconsin to the west, mostly across Lake Michigan and Lake Superior with a short land line through the western Upper Peninsula; Indiana and Ohio along the southern edge of the Lower Peninsula; and the Canadian province of Ontario across the water the whole way around, the St. Marys River, Lake Huron, the St. Clair River, Lake St. Clair, the Detroit River, and Lake Erie. Few states touch this much water on this many sides, which is exactly why so many county lines on the map trace a shoreline instead of a straight survey line.
Road-light orientation: Light corridor cues for I-75, I-94, I-96, US-31, US-131, US-2, US-41, and M-28 help place the big metro anchors the cartography marks clearly: Detroit in Wayne County, Grand Rapids in Kent County, Warren and Sterling Heights in Macomb County, and the state capital, Lansing, mostly in Ingham County. Look at the map and you'll notice these roads stay thin on purpose, they exist to help you find your place, not to plan a turn-by-turn drive.
Start at the Wisconsin line on the shore of Lake Superior. Gogebic County, seat Bessemer, anchors the far west with the ski-and-woods towns of Ironwood and Wakefield along the Montreal River highlands. East along the lake, Ontonagon County, seat Ontonagon, is a large forested county shaped by the Porcupine Mountains and a long shoreline. The Keweenaw Waterway splits Houghton County, seat Houghton, from the base of the Keweenaw Peninsula, with Hancock, Calumet, and Laurium labeled up the spine toward Copper Harbor. Keweenaw County, seat Eagle River, is the thin northernmost wedge, Michigan's least populous county but its largest by total area once Lake Superior water is counted. Across Keweenaw Bay, Baraga County, seat L'Anse, faces Baraga across the water while the Huron Mountains rise inland. South of the copper country, Iron County, seat Crystal Falls, and Dickinson County, seat Iron Mountain, mark the mining belt along the Wisconsin border, with Norway and Kingsford labeled near Dickinson's Menominee River corridor. Menominee County, seat Menominee, closes out the southern tier on Green Bay, opposite Marinette, Wisconsin.
East of Menominee, Delta County, seat Escanaba, wraps around Little Bay de Noc with Gladstone and Rapid River along the shore. Marquette County, seat Marquette, is the Upper Peninsula's most populous county and Michigan's largest by land area, with Ishpeming and Negaunee inland and a light US-41/M-28 line running toward Munising. Alger County, seat Munising, anchors Pictured Rocks country, while Schoolcraft County, seat Manistique, sits on the northern rim of Lake Michigan. Luce County, seat Newberry, reaches north to Whitefish Bay, and Chippewa County, seat Sault Ste. Marie, is where the St. Marys River locks and the international crossing to Ontario dominate the map, with Kincheloe and Rudyard along a faint I-75 cue. Mackinac County, seat St. Ignace, closes the peninsula at the Mackinac Bridge, with Mackinac Island noted just offshore.
South of the bridge, Emmet County, seat Petoskey, leads with Harbor Springs, Alanson, and Mackinaw City at the county corner along Little Traverse Bay. Cheboygan County, seat Cheboygan, sits on the river to Lake Huron, with Indian River and Wolverine inland. Presque Isle County, seat Rogers City, and Alpena County, seat Alpena, run the long Huron shoreline past Thunder Bay. Inland, Montmorency County, seat Atlanta, and Otsego County, seat Gaylord, sit astride the light I-75 axis. Back on the Lake Michigan side, Charlevoix County, seat Charlevoix, pops between Lake Charlevoix and Little Traverse Bay, with Boyne City and East Jordan inland, and Antrim County, seat Bellaire, is tucked into Chain-of-Lakes country with Elk Rapids, Mancelona, and Central Lake labeled.
Leelanau County's seat moved from Leland to Suttons Bay Township in 2008; the map still labels Leland, Northport, and Suttons Bay village along the peninsula's pastel shoreline. Grand Traverse County, seat Traverse City, dominates the bay with Acme and Kingsley nearby. Benzie County, seat Beulah, is Michigan's smallest county by land area, with Frankfort on Lake Michigan and Crystal Lake inland. Manistee County, seat Manistee, appears at the harbor with Onekama nearby, and Wexford County, seat Cadillac, and Missaukee County, seat Lake City, sit along the light US-131 corridor with Manton and McBain labeled.
Kalkaska County, seat Kalkaska, lies between Traverse City and Grayling. Crawford County, seat Grayling, and the Au Sable headwaters sit on a soft I-75 line. Oscoda County, seat Mio, and Ogemaw County, seat West Branch, use river bends and a light I-75 cue for orientation, with Rose City labeled near Ogemaw. Roscommon County, seat Roscommon, centers on the Houghton Lake basin. Iosco County, seat Tawas City, shows Tawas City and East Tawas on Tawas Bay, with Oscoda up the coast, and Alcona County, seat Harrisville, sits on the pastel Huron shore with Lincoln nearby.
At the mouth of Saginaw Bay, Arenac County, seat Standish, shows Au Gres along a faint US-23 trace. The Tri-Cities cluster tightly: Bay County, seat Bay City, spans the Saginaw River mouth with Essexville on the east bank; Midland County, seat Midland, shows Sanford among rivers and reservoirs; Saginaw County, seat Saginaw, labels Birch Run with I-75 shown faintly between Flint and the Tri-Cities. Thumb country begins at Tuscola County, seat Caro, with Vassar and Cass City labeled, continues to Huron County, seat Bad Axe, at the Thumb's tip with Harbor Beach, Port Austin, and Caseville, and wraps to Sanilac County, seat Sandusky, with Marlette, Lexington, and Port Sanilac on the central Thumb. Lapeer County, seat Lapeer, and Genesee County, seat Flint, close this region on the Detroit fringe, with Grand Blanc, Davison, Mt. Morris, and Fenton shown around Flint on a thin I-69/I-475 mesh.
Clare County, seat Harrison, marks the crossing where US-127 and US-10 meet lightly on the map, with Clare itself at the junction. Gladwin County, seat Gladwin, sits along the Tittabawassee watershed with Beaverton nearby. Mecosta County, seat Big Rapids, and Osceola County, seat Reed City, line the subtle US-131 alignment with Evart and Hersey labeled. Newaygo County, seat White Cloud, and Lake County, seat Baldwin, sit in river-valley and forest-lakes country with Fremont, Newaygo, and Idlewild noted. Montcalm County, seat Stanton, and Gratiot County, seat Ithaca, show Greenville, Howard City, and Alma along US-127's light line, and Isabella County, seat Mount Pleasant, is central Michigan's college-town county with Shepherd nearby.
On the coast, Mason County, seat Ludington, and Oceana County, seat Hart, show Scottville, Shelby, and Pentwater along the fruit belt. Muskegon County, seat Muskegon, labels Norton Shores and Whitehall around Muskegon Lake, and Ottawa County, seat Grand Haven, shows Holland's west side, Zeeland, and Coopersville along a faint US-31/I-196 corridor. Allegan County, seat Allegan, spans the Lake Michigan-to-Kalamazoo gap with Saugatuck and Plainwell noted. Inland, Kent County, seat Grand Rapids, is the anchor of West Michigan with Wyoming, Kentwood, Walker, Rockford, and Lowell shown on a soft I-96/I-196/US-131 mesh, while Ionia County, seat Ionia, and Barry County, seat Hastings, fill the Grand River corridor between Grand Rapids and Lansing.
Clinton County, seat St. Johns, and Eaton County, seat Charlotte, ring the Lansing metro with DeWitt, Bath, Grand Ledge, and Eaton Rapids labeled. Ingham County, seat Mason, carries the state capital: Lansing is labeled prominently even though the county seat itself is Mason, with East Lansing, Okemos, Williamston, and Holt also shown. Livingston County, seat Howell, and Shiawassee County, seat Corunna, connect Lansing toward Flint and metro Detroit, with Brighton and Owosso noted along a light I-96/I-69 cue.
Van Buren County, seat Paw Paw, and Berrien County, seat St. Joseph, hold the southwest lakeshore, with South Haven, Hartford, Bangor, Benton Harbor, Niles, Bridgman, and New Buffalo all labeled along a light I-94/US-31 cue toward Indiana. Cass County, seat Cassopolis, and St. Joseph County, seat Centreville, sit near the Indiana line with Dowagiac, Edwardsburg, Three Rivers, and Sturgis on a faint US-131 axis. Branch County, seat Coldwater, and Kalamazoo County, seat Kalamazoo, with Portage and Galesburg labeled, anchor the I-94 corridor, and Calhoun County, seat Marshall, shows Battle Creek as the metro anchor with Albion on the county's east side.
Jackson County, seat Jackson, sits on a faint I-94 line with Michigan Center and Grass Lake nearby, and Washtenaw County, seat Ann Arbor, bolds Ann Arbor and Ypsilanti with Saline, Chelsea, and Milan also clear. South along the Ohio line, Hillsdale County, seat Hillsdale, and Lenawee County, seat Adrian, show Jonesville, Reading, Tecumseh, Hudson, and Blissfield, while Monroe County, seat Monroe, occupies the Lake Erie and River Raisin shore with Temperance, Luna Pier, and Carleton on a thin I-75 line to Detroit and Ohio. Wayne County, seat Detroit, anchors the whole southeast, with Dearborn, Livonia, Westland, Taylor, Wyandotte, and the Grosse Pointe communities labeled on light I-75/I-94/I-96/M-10 cues. Oakland County, seat Pontiac, and Macomb County, seat Mount Clemens, complete the metro ring: Oakland shows Troy, Royal Oak, Farmington Hills, Bloomfield, Rochester, and Novi, while Macomb hugs the Lake St. Clair shore with Warren, Sterling Heights, Clinton Township, St. Clair Shores, and New Baltimore. St. Clair County, seat Port Huron, closes the state at the Canadian gateway, with Marysville, St. Clair, and Marine City where the St. Clair River forms the border.
Three Great Lakes and one narrow strait do most of the orientation work on this page. Lake Michigan traces the entire western edge of both peninsulas, past Menominee, Ludington, and Benton Harbor. Lake Huron shapes the northeast and the Thumb, past Alpena, Bay City, and Port Huron. Lake Superior rims the Upper Peninsula's north shore past Marquette and the Keweenaw. The Straits of Mackinac, spanned by the Mackinac Bridge, ties the two peninsulas together at Mackinaw City and St. Ignace. Inland, the Grand River, Michigan's longest, runs through Lansing and Grand Rapids to Lake Michigan, while the Saginaw River system drains the Thumb and Tri-Cities into Saginaw Bay. Keep these landmarks in mind and any county on the map is easy to place.
The road layer is intentionally minimal. I-75 runs Detroit-Flint-Saginaw-Bay City-Grayling-Gaylord-Cheboygan-St. Ignace-Sault Ste. Marie, crossing the Straits on the Mackinac Bridge. I-94 runs Detroit-Ann Arbor-Jackson-Battle Creek-Kalamazoo-Benton Harbor/St. Joseph toward Indiana, and separately continues east from Detroit to Port Huron. I-96 runs Detroit-Lansing-Grand Rapids-Muskegon, with I-196 branching to Holland and South Haven. US-131 runs Kalamazoo-Grand Rapids-Big Rapids-Cadillac-Petoskey, and US-31 follows the Lake Michigan shoreline in roughly the same direction. In the Upper Peninsula, US-2 crosses the south, US-41 runs Menominee-Marquette-Keweenaw, and M-28 tracks the Lake Superior shore. None of these are meant for turn-by-turn navigation, only as county-placement cues.

Michigan borders Wisconsin to the west, mostly across Lake Michigan and Lake Superior with a short land line through Gogebic, Iron, Dickinson, and Menominee counties, Indiana and Ohio along the southern edge of the Lower Peninsula, and the Canadian province of Ontario across the St. Marys River, Lake Huron, the St. Clair River, Lake St. Clair, the Detroit River, and Lake Erie. The state holds 83 counties split across two peninsulas joined only by the Straits of Mackinac. Marquette County is the largest by land area at about 1,808 square miles, while Benzie County is the smallest at about 321 square miles. Wayne County, home to Detroit, is the most populous at roughly 1,771,063 residents, and Keweenaw County is the least populous at roughly 2,161 residents. Wayne County is also the oldest, established in 1796, decades before Michigan reached statehood in 1837. Michigan covers about 96,716 square miles in total, making it one of the largest states east of the Mississippi once its Great Lakes waters are counted. The capital, Lansing, sits mostly in Ingham County, and the state's major metros run from Detroit and its suburbs through Grand Rapids, Lansing, Ann Arbor, and Flint to the smaller hubs of Kalamazoo, Saginaw, and Traverse City. Landscape-wise, the Lower Peninsula's mitten shape moves from farmland in the south through rolling forest and lake country in the north, while the Upper Peninsula carries rugged ridges, copper country, and the state's highest ground near Lake Superior.
Michigan's ten largest cities by current population are Detroit (about 633,218, Wayne County), Grand Rapids (about 196,608, Kent County), Warren (about 136,655, Macomb County), Sterling Heights (about 133,306, Macomb County), Ann Arbor (about 119,381, Washtenaw County), Lansing (about 112,115, Ingham County), Dearborn (about 105,811, Wayne County), Livonia (about 92,185, Wayne County), Troy (about 87,339, Oakland County), and Westland (about 82,574, Wayne County). Detroit and its Wayne, Oakland, and Macomb County suburbs anchor the state's automotive heritage, home to General Motors, Ford, and Stellantis alongside a deep bench of parts suppliers and, increasingly, mobility and battery technology firms. Ann Arbor centers a research and technology corridor around the University of Michigan, while Grand Rapids anchors West Michigan's furniture, healthcare, and manufacturing base. Battle Creek remains tied to food processing, and Midland is home to Dow's global headquarters. Agriculture runs strong outside the metro areas too, with the fruit belt along the Lake Michigan shore producing cherries, apples, and blueberries, and dairy and field crops spread across the central and Thumb counties. Tourism follows the water: Great Lakes shoreline towns, Mackinac Island, and the north woods draw visitors across all four seasons.
Michigan's cultural identity runs through its counties as much as its cities. Detroit's Motown Records, founded in Wayne County in 1959, shaped American popular music and remains a touchstone of the city's identity alongside its deep automotive history. The Woodward Dream Cruise, one of the world's largest one-day car events, runs each August through Oakland County along the road that gave Detroit's auto industry its early proving ground. Michigan's maritime heritage centers on the Great Lakes freighters that still move iron ore and grain past Sault Ste. Marie's Soo Locks in Chippewa County, and lighthouses ring the coastline from the Keweenaw to the Thumb. Mackinac Island, reached from both Mackinac and Cheboygan Counties at the Straits, preserves a car-free, fudge-and-Victorian-hotel tourist tradition dating to the 1800s. Higher education is spread widely too, with the University of Michigan in Ann Arbor (Washtenaw County), Michigan State University in East Lansing (Ingham County), Michigan Technological University in Houghton, and Northern Michigan University in Marquette anchoring the Upper Peninsula.
On this map, Mount Arvon (Huron Mountains, Baraga County) and Lake Michigan, Lake Huron, and Lake Superior double as landmarks for finding counties quickly. For elevation, terrain, watersheds, and land-cover detail, see our Physical Map of Michigan.
Michigan has a humid continental climate with warm summers and cold, snowy winters, and the Great Lakes bring heavy lake-effect snow to the western Upper Peninsula and the western Lower Peninsula while moderating temperatures near the shorelines. For a full seasonal and biome breakdown, see our Physical Map of Michigan.
North-south travel on the Lower Peninsula runs mainly on I-75 (Detroit to Flint, Saginaw, Bay City, Grayling, and Gaylord to the Mackinac Bridge) and US-131 (Kalamazoo to Grand Rapids, Big Rapids, Cadillac, and Petoskey). East-west travel runs on I-94 (Detroit to Ann Arbor, Jackson, Battle Creek, Kalamazoo, and on to Indiana, or east from Detroit to Port Huron) and I-96 (Detroit to Lansing to Grand Rapids to Muskegon). In the Upper Peninsula, US-2, US-41, and M-28 carry the cross-state traffic. Keep in mind that ZIP codes do not follow county lines in Michigan, so a single ZIP code can span two counties. Always confirm the county name directly from the map or index rather than assuming it from a ZIP prefix.
Use this as a quick index. Every line lists the county with its county seat and a short river, border, or corridor cue.
