Wesley Jonell-Cleavon Bell (born November 5, 1974) is an American attorney and politician serving as the U.S. representative for Missouri's 1st congressional district since 2025. A member of the Democratic Party, he previously served as prosecuting attorney for St. Louis County, Missouri, from 2019 to 2025. In a major upset, he defeated long-time yet controversial county prosecutor Bob McCulloch in the August 2018 Democratic primary election, and became the first Black county prosecuting attorney in St. Louis County history when he took office in January 2019. On June 7, 2023, Bell announced his candidacy in the 2024 United States Senate election in Missouri. In October 2023, he instead opted to run for the U.S. House seat of Missouri's 1st congressional district, defeating incumbent Cori Bush in the Democratic primary in August 2024 and winning the general election in November.
