Thierry Champion (born 31 August 1966) is a former professional tennis player from France.

A clay court specialist, Champion gained notoriety on the men's ATP tour as a wild card player with the ability to inflict defeat on seeded players well above his ranking.

44 on the men's ATP rankings in 1991, subsequent years saw a dwindling career riddled with injury.

One of the worst Grand Slam defeats in tennis history came when Champion was triple bageled, losing 6–0, 6–0, 6–0 in the 2nd round of the 1993 French Open, by eventual winner Sergi Bruguera.

At the 2008 Wimbledon Championships he was seen to be coaching French player Richard Gasquet for a short stint.
