Michigan's 6th congressional district is a United States congressional district in southwest Michigan. It consists of all of Berrien, Cass, Kalamazoo, St. Joseph, and Van Buren, counties, and includes most of Allegan county. Its largest city is Kalamazoo. 2011 redistricting removed the portion of Calhoun County that had been in the district, and added northwestern Allegan County, leaving only parts of the city of Holland in the 2nd district.
