Charles "Buddy" Montgomery (January 30, 1930 – May 14, 2009) was an American jazz vibraphonist and pianist. He was the younger brother of Wes and Monk Montgomery, a guitarist and bassist respectively.
Buddy and brother Monk formed The Mastersounds in the late 1950s and produced ten recordings. When The Mastersounds disbanded, Monk and Buddy joined their brother Wes on a number of Montgomery Brothers recordings, which were mostly arranged by Buddy. They toured together in 1968, and it was in the middle of that tour that Wes died. Buddy continued to compose, arrange, perform, produce, teach and record, producing nine recordings as a leader.
