Wesley Thompson (born October 2, 1956) appeared as an Army Corpsman in the Season 11 episode of M*A*S*H titled "As Time Goes By". Wesley's other TV series guest appearances include The White Shadow, The Larry Sanders Show, Boston Legal, and Seinfeld. He has degrees in Theater Arts from San Francisco State University & UCLA.

Born in Chicago, IL and raised in Pasadena, CA, Wesley began his career on the stage. He was voted Best Actor in college for his leading role in prolific playwright and director George C. Wolfe's very first play, "Up For Grabs". he's performed all over the Southland in such roles as Honey in "A Member of the Wedding" (with Virginia Capers), convicted felon Ice in Miguel Pinero's prison drama "Short Eyes", and in three long-running productions at West LA's Odyssey Theater: Filtch in Molière's "The Miser" with George Murdock, soldier McGlade in a Vietnam drama, "The Bridgehead", directed by Stephen Tobolowsky, and wisecracking relief pitcher Duke in the baseball comedy hit, "Bullpen", which moved, after its initial run, to Boston's Hasty Pudding Theater at Harvard. He has since gone on to do dozens of plays all over, but none as rewarding as his supporting role as the lovable loan shark Jumbo in the 2000 production of the romantic-comedy "Panache". It opened at the Pasadena Playhouse but within two months was swiftly moved to off-Broadway, to the Players Theater in Greenwich Village, in which The New York Times called Wesley "an electric, on-stage presence".

He was a series regular on two ABC programs: He's the Mayor (1986) and Pursuit of Happiness (1987). His most recent stints include Friends (1994), Providence (1999), Just Shoot Me! (1997), Malcolm in the Middle (2000) and recurring roles on ER (1994) and Grounded for Life (2001). He has been very fortunate to have done over 200 commercials over the years.

His first audition for film was for a low-budget drama intended as a documentary where the actors had to be believed as real people. The director, a young newcomer to feature filmmaking, hired him on the spot. The director, Taylor Hackford ("An Officer and a Gentleman", "The Devil's Advocate"). The film, "Teenage Father" (1978), won the Academy Award as Best Live Action Short.
