The 13th Assembly district of Wisconsin is one of 99 districts in the Wisconsin State Assembly. Located in southeast Wisconsin, the district comprises parts of western Milwaukee County and eastern Waukesha County. It contains most of the city of Wauwatosa, along with the village of Elm Grove and much of northern Brookfield. The district also contains landmarks such as the Medical College of Wisconsin, Froedtert Hospital, Mayfair Mall, and Webster Park. The district is represented by Democrat Robyn Vining, since January 2025; Vining previously represented the 14th district from 2019 to 2025.
The 13th Assembly district is located within Wisconsin's 5th Senate district, along with the 14th and 15th Assembly districts.
History The district was created in the 1972 redistricting act (1971 Wisc. Act 304) which first established the numbered district system, replacing the previous system which allocated districts to specific counties. The 13th district was drawn somewhat in line with the western half of the previous Milwaukee County 18th district, though with some city of Milwaukee wards removed, and the village of Butler in Waukesha County added.
The district has remained in the same vicinity since 1972, but the boundaries have moved further and further west. By 2011, the district contained only a small portion of the city of Milwaukee; the 2022 redistricting saw the district move even further west, putting it almost entirely within Waukesha County. The 2024 redistricting act moved the district back to the east, re-adding most of the city of Wauwatosa and shedding a large part of the city of Brookfield.
