Michigan's 11th congressional district is a United States congressional district north of Detroit, comprising most of urbanized central Oakland County. Until 1993, the district covered the state's Upper Peninsula and the northernmost portion of the Lower Peninsula. In redistricting that year, it was shifted to the outer Detroit area. Its former geographical area is now the state's first district. Its current configuration dates from 2023.
