Matthew Wilder (born Matthew Weiner on January 24, 1953 in Manhattan, New York City) is an American musician best known for his 1983 hit "Break My Stride".

Wilder was one-half of the Greenwich Village folk group Matthew & Peter in the 1970s. In 1978 he moved to Los Angeles and sang for television commercials and backup for Rickie Lee Jones and Bette Midler.

Wilder's first album, I Don't Speak the Language (1983), reached number 49 on the Billboard chart, fueled by "Break My Stride", which reached number 5 on the singles chart. His second album, Bouncin' Off the Walls (1984), was a commercial failure.

Wilder continued his career as a songwriter and producer. His work includes producing the No Doubt's multi-platinum album Tragic Kingdom (1995). He lent his singing voice to the character of Ling and was nominated for an Academy Award for Original Music Score (along with David Zippel and Jerry Goldsmith) for his work on the Disney film Mulan (1998).

On Broadway, Wilder has once again paired with Zippel to provide the music and lyrics for Princesses, a musical comedy update of Frances Hodgson Burnett's novel A Little Princess. The production is slated to open on Broadway in November 2006.
