Each Wisconsin State Senate district is composed of three Wisconsin State Assembly districts. The 15th Senate district comprises the 43rd, 44th, and 45th Assembly districts. The current representatives of those districts are:[4]
- Assembly District 43: Jenna Jacobson (D–Oregon)

The 15th Senate district, in its current borders, crosses three different congressional districts. The portion of the district in Jefferson County falls within Wisconsin's 5th congressional district, which is represented by U.S. Representative Scott L. Fitzgerald; the portion in Walworth County and the cities of Janesville and Milton and the eastern part of Rock County fall within Wisconsin's 1st congressional district, which is represented by U.S. Representative Bryan Steil; the remainder of the district, in the western half of Rock county, falls within Wisconsin's 2nd congressional district, which is represented by U.S. Representative Mark Pocan.[5]
