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.

After a period in the Army, where he had his own quartet, he joined The Mastersounds as a vibraphonist with his brother Monk, pianist Richie Crabtree and drummer Benny Barth in 1957.

After Wes Montgomery's death in 1968, Buddy became active as a jazz educator and advocate.
