The 13th Senate district of Wisconsin is one of 33 districts in the Wisconsin Senate. Located in south central Wisconsin, the district comprises all of Green Lake and Marquette counties, along with most of Dodge County, western Fond du Lac County, and parts of northern Jefferson County, eastern Adams County, northeast Columbia County, and southwest Winnebago County. It includes the cities of Beaver Dam, Horicon, Markesan, Mayville, Montello, Princeton, Ripon, Watertown, and Waupun.

## Current elected officials

John Jagler is the senator representing the 13th district. He was first elected in a 2021 special election. He previously served 8 years in the State Assembly.
