The 2021 Wisconsin Superintendent of Public Instruction election was a nonpartisan state-wide election held on April 6, 2021, to elect the Superintendent of Public Instruction of Wisconsin for a four-year term. The election was won by Jill Underly, the superintendent of the Pecatonica Area School District, defeating former Brown Deer School District superintendent Deborah Kerr.
The incumbent superintendent, Carolyn Stanford Taylor, did not run for election to a full term; she had been appointed to the office in 2019 by governor Tony Evers. Evers had been the previously-elected superintendent, but resigned on January 7, 2019, after he was elected governor of Wisconsin.
Underly and Kerr advanced to the general election as the top two vote-getters in the February 16, 2021, nonpartisan primary, receiving 27% and 26% of the votes, respectively. Five other candidates were eliminated in the primary.
