Michigan's 9th Senate district


Michigan's 9th Senate district is one of 38 districts in the Michigan Senate. The 9th 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 Republican Michael Webber since 2023, succeeding Democrat Paul Wojno.
