Al Thornton (born December 7, 1983, in Perry, Georgia) is an American professional basketball player for the NBA's Los Angeles Clippers. Collegiately, he played for Florida State University.

Al Thornton's outstanding four-year career at Florida State University was capped off by a stellar individual senior year that saw him make the AP Third-Team All-American, a unanimous selection to the First-Team All-ACC team, and was runner up to Boston College's Jared Dudley for the ACC Player of the Year. He led the ACC in scoring and averaged over 7 rebounds per game as well. His season came to a disappointing end as the Seminoles did not qualify for the NCAA tournament for the ninth straight season and were forced to play in the NIT.

On June 28, 2007, Thornton was taken 14th overall in the 2007 NBA Draft by the Los Angeles Clippers. Thornton also has the same agent as Yao Ming. On July 9, Thornton played his first summer league game for the Clippers, scoring 24 points and registering 8 rebounds, 1 assist, and 2 blocks in a 102–108 loss to the Denver Nuggets.
