Walter Davis Jr. (September 2, 1932 – June 2, 1990) was an American bebop and hard bop pianist.

Davis once left the music world to be a tailor, but returned. A soloist, bandleader, and accompanist, he amassed a body of work while never becoming a high-profile name even within the jazz community. Davis played with Babs Gonzales' Three Bips & a Bop as a teen, then moved from Richmond to New York in the early 1950s. He played with Max Roach and Charlie Parker, recording with Roach in 1953.

He joined Dizzy Gillespie's band in 1956, and toured the Middle East and South America. He also played in Paris with Donald Byrd in 1958 and with Art Blakey & the Jazz Messengers in 1959.

After retiring from music for a while to run his tailor shop, Davis returned in the 1960s, producing records and writing arrangements for a local New Jersey group. He studied music in India in 1979, and played with Sonny Rollins in the early 1970s.
