M-10 is a north–south state trunkline highway in the Metro Detroit area of Michigan in the United States. The southernmost portion follows Jefferson Avenue in downtown Detroit, and the southern terminus is at the intersection of Jefferson and M-3 (Randolph Street) next to the entrance to the Detroit–Windsor Tunnel. The northern terminus is in West Bloomfield Township at the intersection with Orchard Lake Road. The highway has several names as it runs through residential and commercial areas of the west side of Detroit and into the suburb of Southfield. It is called the John C. Lodge Freeway, The Lodge, James Couzens Highway and Northwestern Highway.

M-10 was built in segments through the late 1950s and early 1960s. It carried several different names before the entire route was finally officially named the John C. Lodge Freeway in 1987. The freeway has carried a few other highway designations. The southern segment was part of US Highway 12 (US 12) and the whole thing was later renumbered Business Spur Interstate 696 (BS I-696). From 1970 until 1986, it was part of US 10, and the freeway has been M-10 since. The non-freeway segment that runs between I-696 in Southfield and Orchard Lake Road was previously numbered M-4. M-10 was named after John C. Lodge, an influential Detroiter and Mayor of Detroit from 1927–28.
