Michigan's 17th Senate district

Michigan's 17th Senate district is one of 38 districts in the Michigan Senate. The 17th 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 Jonathan Lindsey since 2023, succeeding fellow Republican Dale Zorn.
