NotesEastern Wisconsin

The 20th Senate district of Wisconsin is one of 33 districts in the Wisconsin Senate.[1] Located in eastern Wisconsin, the district comprises most of Washington County, northern Ozaukee County, and parts of southern Sheboygan County, eastern Fond du Lac County, and eastern Dodge County. It includes the cities of Fond du Lac and West Bend, and the villages of Belgium, Cedar Grove, Fredonia, North Fond du Lac, Saukville, and Slinger.[2]

Current elected officials

Dan Feyen is the senator representing the 20th district. He was first elected in 2016 in the 18th Senate district, but ran for election in the 20th district after the 2024 redistricting.[3]

Each Wisconsin State Senate district is composed of three State Assembly districts. The 20th Senate district comprises the 58th, 59th, and 60th Assembly districts. The current representatives of those districts are:[4]

The 20th Senate district, in its current borders, crosses two congressional districts. The portion of the district in Dodge and Washington counties falls within Wisconsin's 5th congressional district, which is represented by U.S. Representative Scott L. Fitzgerald. The remainder of the district, in Ozaukee, Sheboygan, and Fond du Lac counties, falls within Wisconsin's 6th congressional district, represented by U.S. Representative Glenn Grothman.[5]

The district has previously been represented by:[6]

Note: the boundaries of districts have changed repeatedly over history. Previous politicians of a specific numbered district have represented a completely different geographic area, due to redistricting.
