Ever driven from the bottom of the Mitten all the way up to the tip of the Keweenaw Peninsula? If you have, you know Michigan is huge. It’s a massive, sprawling collection of peninsulas, islands, and forests. But when you look at a map, it’s the grid lines that really tell the story. People always ask, "Wait, how many counties in the state of Michigan are there, exactly?"
The answer is 83.
Honestly, that number feels like a lot when you realize California—which is nearly triple the size—only has 58. Michigan’s county system is a dense, historical patchwork that was basically finished by the late 1800s. It’s a mix of massive wilderness blocks in the Upper Peninsula (U.P.) and tiny, packed-in squares down south.
Why 83? A Messy History of Naming and Renaming
Michigan didn't just wake up one day with 83 counties. Back in the late 1700s, Wayne County (the one Detroit calls home) actually covered almost the entire state, plus parts of what are now Ohio, Indiana, and Illinois. Imagine the commute to the county seat for those folks.
As the population boomed, the state legislature started carving things up. They used a "two-stage" process. First, they’d draw a box on a map and give it a name—this was called "setting off" a county. Then, years later, when enough people lived there, they’d officially "organize" it with its own government.
Things got weird in 1840. The legislature "set off" a bunch of counties in the northern Lower Peninsula and gave them Native American-sounding names like Negwegon, Anamickee, and Okkuddo. Just three years later, they changed their minds and renamed most of them after Irish figures or local politicians. That’s why we have Alcona, Alpena, and Otsego today instead of the original names.

The very last one to join the club was Dickinson County in the U.P., which was organized in 1891. Since then? Total silence. The map has stayed the same for over 130 years.
The Giants vs. The Tiny Spots
When you talk about how many counties in the state of Michigan exist, you’re really talking about two different worlds.
Take Marquette County. It’s the king of the U.P. in terms of size. We’re talking over 1,800 square miles of land. It’s bigger than the entire state of Rhode Island. If you’re hiking in Marquette, you could walk for days and never leave the county line.
On the flip side, you’ve got Benzie County. It’s the smallest by land area, tucked away on the Lake Michigan shore. It’s only about 320 square miles. You can drive across it in the time it takes to finish a medium coffee.
Then there’s the population gap, which is honestly staggering.

- Wayne County: Home to nearly 1.8 million people. It’s the heavyweight champion.
- Keweenaw County: The tiny tip of the U.P. has fewer than 2,200 residents.
Think about that for a second. There are single apartment buildings in Detroit with more people than the entire county of Keweenaw.
What Do These 83 Counties Actually Do?
You might think counties are just for addresses or license plate tabs, but they’re the "middle management" of the state. Most Michigan counties run on what’s called "General Law." Basically, the state tells them what they can and can’t do.
They handle the "un-fun" but vital stuff:
- The Courts: Circuit and Probate courts are usually county-run.
- Records: If you get married, buy a house, or... well, die... the county Clerk or Register of Deeds is the one filing the paperwork.
- Sheriff's Office: In rural areas, the County Sheriff is often the primary law enforcement.
- Health Departments: This became a huge deal during the pandemic. Some smaller counties, especially in the north, actually share a health department because they don't have enough people to run their own.
Only two counties—Wayne and Oakland—have a "Charter" or "Unified" government with an elected County Executive. Most others are run by a Board of Commissioners who hire an administrator. It’s a bit more "old school."
The Counties That Vanished
Did you know Michigan used to have counties that don't exist anymore? It's true.

There was once an Isle Royale County. Yes, the island in Lake Superior was its own county for about 15 years in the late 1800s. Eventually, they realized having a whole government for a remote island was a logistical nightmare, so they folded it into Keweenaw County.
There was also Manitou County, which covered the Beaver Island archipelago and the Fox Islands. It was abolished in 1895 because of... well, let's just say "political irregularities" and a very small population. The islands were split between Charlevoix and Leelanau.
Future Outlook: Will the Number Ever Change?
Probably not. While some experts argue that merging counties in the U.P. would save taxpayers money, local pride is a powerful thing. People identify with their county. Whether you're a "Yooper" from Iron County or a "Trolley-dodger" from Kent, that 83-county map is baked into the Michigan identity.
Population trends are shifting, though. While Grand Traverse and Ottawa counties are booming, many rural counties are seeing their populations age and shrink. By 2050, some projections show that the vast majority of those 83 counties will have fewer people than they do today.
Actionable Takeaway for Your Next Trip
If you’re planning a Michigan road trip or looking to move, don't just look at the cities. Each of the 83 counties has its own "vibe" and legal quirks.
- Check the County Parks: Often, county parks (like those in Oakland or Kent) are better maintained than state parks and much less crowded.
- Property Research: If you’re buying land, remember that property tax rates vary wildly between counties—even if the houses are just a mile apart across a border.
- Historical Society Stops: Most of the 83 counties have a small museum in their county seat (like Howell for Livingston or Paw Paw for Van Buren). These are gold mines for local stories you won't find on Wikipedia.
So, the next time someone asks how many counties in the state of Michigan, you can tell them it’s 83—and that each one has a story that’s been over a century in the making.
