Incumbent Republican Lieutenant Governor Mike Kehoe did not run for reelection for a second full term, and instead ran successfully for Governor of Missouri. The filing deadline was March 26, 2024, with primaries being held on August 6. Republican attorney David Wasinger and Democratic state Representative Richard Brown won their parties' respective primaries, and faced each other in the general election.
