Carlos Wesley “Don” Byas (October 21, 1912 – August 24, 1972) was an American jazz tenor saxophonist, most associated with bebop. He played with Count Basie, Duke Ellington, Art Blakey, and Dizzy Gillespie, among others, and also led his own band. He lived in Europe for the last 26 years of his life.

Byas was born in Muskogee, Oklahoma. Both of Byas’ parents were musicians. His mother played the piano, and his father, the clarinet. Byas started his training in classical music, learning to play violin, clarinet and alto saxophone, which he played until the end of the 1920s.
