Timothy Eugene Scott (born September 19, 1965) is an American businessman and politician serving since 2013 as the junior United States senator from South Carolina. A member of the Republican Party, he is the first African-American senator in the Southern United States to be directly elected, the longest-serving Black senator in U.S. history, the first Black American to serve in both the House and Senate, and the first Black senator to chair a full committee.

Born and raised in Charleston, Scott worked in financial services before entering politics. He served on the Charleston County Council from 1995 to 2009, was a member of the South Carolina General Assembly from 2009 to 2011, and represented South Carolina's 1st congressional district in the U.S. House of Representatives from 2011 to 2013.

In May 2023, Scott declared his candidacy for the 2024 Republican Party presidential nomination. He suspended his campaign in November due to low polling numbers.
