US Highway 10 (US 10) is a part of the United States Numbered Highway System that runs from West Fargo, North Dakota, to the Lower Peninsula of the US state of Michigan. The highway enters Michigan on SS Badger, which crosses Lake Michigan between Manitowoc, Wisconsin, and Ludington. As the highway crosses the state, it is a two-lane undivided highway between Ludington and Farwell and a freeway from Farwell east to the highway's terminus in Bay City. US 10 runs concurrently with US 127 in the Clare area along a section of freeway that includes a welcome center in the median. Outside of the Clare and Midland areas, US 10 runs through rural areas of West and Central Michigan in a section of the Manistee National Forest as well as farmfields.

As part of the original US Numbered Highway System, US 10 was first designated in Michigan in 1926. It replaced three state trunkline highways of the day: M-20, M-24, and M-10, running between Ludington on Lake Michigan and downtown Detroit. It also ran concurrently with US 23 between Saginaw and Flint. The highway has been realigned several times during the construction of Interstate 75 (I-75) in southeast Michigan, even being temporarily designated "TO I-75" to connect segments of the I-75 freeway. The US 10 freeway between Clare and Midland was opened in the early 1960s. The Michigan Department of Transportation (MDOT) truncated the highway to Bay City in 1986, removing it from I-75 and the Lodge Freeway.
