Largest and smallest counties

Marquette County is the largest county at 1,809.1 sq mi of land, followed by Chippewa County (1,558.5 sq mi) and Ontonagon County (1,311.0 sq mi). Benzie County, on Lake Michigan in the northwestern Lower Peninsula, is the smallest at 319.7 sq mi. Because counties extend into the Great Lakes, many have far more total area than land: Keweenaw County covers 5,966.3 sq mi in total but only 540.1 sq mi of land.

Counties in the two peninsulas

Michigan’s counties are split between its two peninsulas: 15 in the Upper Peninsula and the rest in the Lower Peninsula. Counties are divided into townships and cities, and each county has an elected board of commissioners.

Michigan uses two time zones by county: Gogebic, Iron, Dickinson and Menominee counties, along the Wisconsin border, use Central Time; the rest of the state uses Eastern Time.
