Roy Owen Haynes (born March 13, 1925) is an American jazz drummer. He is among the most recorded drummers in jazz. In a career lasting over 75 years he has played swing, bebop, jazz fusion, avant-garde jazz and is considered a father of modern jazz drumming. “Snap Crackle” was a nickname given to him in the 1950s.

He has led bands such as the Hip Ensemble. His albums Fountain of Youth and Whereas were nominated for a Grammy Award. He was inducted into the Modern Drummer Hall of Fame in 1999. His son Graham Haynes is a cornetist; his son Craig Holiday Haynes and grandson Marcus Gilmore are both drummers.

Haynes was born in the Roxbury section of Boston, Massachusetts. His younger brother, Michael E. Haynes, would become an important leader in the black community of Massachusetts, working with Martin Luther King Jr. during the civil rights movement, representing Roxbury in the Massachusetts House of Representatives, and for forty years serving as pastor of the Twelfth Baptist Church, where King had been a member while he pursued his doctoral degree at Boston University.

Haynes made his professional debut in 1944 in his native Boston and began his full-time professional career in 1945. From 1947 to 1949 he worked with saxophonist Lester Young, and from 1949 to 1952 was a member of saxophonist Charlie Parker‘s quintet. He also recorded at the time with pianist Bud Powell and saxophonists Wardell Gray and Stan Getz. From 1953 to 1958 he toured with singer Sarah Vaughan and recorded with her.
