Michigan's 5th Senate district is one of 38 districts in the Michigan Senate. It has been represented by Democrat Dayna Polehanki since 2023, following her primary defeat of fellow Democrat Betty Jean Alexander.
District 5 encompasses part of Wayne County.
District 5, as dictated by the 2011 Apportionment Plan, was based in central Wayne County, covering parts of western Detroit as well as the surrounding communities of Dearborn Heights, Garden City, Inkster, and Redford.
The district was largely located within Michigan's 13th congressional district, also extending into the 12th and 14th districts. It overlapped with the 7th, 8th, 9th, 10th, 11th, and 13th districts of the Michigan House of Representatives.
