Michigan's 20th Senate district is one of 38 districts in the Michigan Senate. The 20th 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 Aric Nesbitt since 2023, succeeding Democrat Sean McCann.
Geography District 20 encompasses parts of Allegan, Berrien, Kent, and Van Buren counties.
2011 Apportionment Plan District 20, as dictated by the 2011 Apportionment Plan, was exactly coterminous with Kalamazoo County, including the city of Kalamazoo and the surrounding communities of Portage, Comstock Northwest, Eastwood, Westwood, Vicksburg, Kalamazoo Township, Oshtemo Township, Texas Township, Comstock Township, and Cooper Township.
The district was located entirely within Michigan's 6th congressional district, and overlapped with the 60th, 61st, 63rd, and 66th districts of the Michigan House of Representatives.
