Michigan's 31st Senate district is one of 38 districts in the Michigan Senate. The 31st district was created by the 1850 Michigan Constitution, as the 1835 constitution only permitted a maximum of eight senate districts.{{cite web|url=https://www.legislature.mi.gov/documents/historical/miconstitution1850.htm |title=CONSTITUTION OF MICHIGAN OF 1850|publisher=Michigan Legislature |accessdate=November 21, 2022}}{{cite web|url=https://www.legislature.mi.gov/documents/historical/miconstitution1835.htm |title=CONSTITUTION OF MICHIGAN OF 1835|publisher=Michigan Legislature |accessdate=November 21, 2022}} It has been represented by Republican Roger Victory since 2023, succeeding fellow Republican Kevin Daley.
