Michigan's 15th Senate district


Michigan's 15th Senate district is one of 38 districts in the Michigan Senate. The 15th district was created by the 1850 Michigan Constitution, as the 1835 constitution only permitted a maximum of eight senate districts. It has been represented by Democrat Jeff Irwin since 2023, succeeding Republican Jim Runestad.
