Michigan's 12th congressional district is a US congressional district in Michigan, which under its current borders stretches from Detroit's western suburbs to Ann Arbor.
The district was first created during the reapportionment and redistricting after the 1890 Census. From 2003 to 2013 it was located in Detroit's inner suburbs to the north, along the Interstate 696 corridor in Macomb and Oakland counties, as well as a portion of Macomb north of the corridor.
