Michigan's 30th Senate district

Michigan's 30th Senate district is one of 38 districts in the Michigan Senate. The 30th 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 Mark Huizenga since 2023, succeeding fellow Republican Roger Victory. By most measures it is the most Republican-leaning district in the Senate.
