Bernard Joseph Baron (born June 26, 1955 in Richmond, Virginia) is an American drummer best-known for working in avant-garde jazz with Bill Frisell and John Zorn.

As a teenager, he played in rock bands and dixieland jazz groups and was given his first gig opportunity at the age of 13 when pianist BJ Doyle's regular drummer took ill and she knew he was a keeper after just minutes.

He moved to Los Angeles in the early 1970s and embarked on a professional career, playing with Carmen McRae and Al Jarreau.

He worked as a freelance drummer and session musician with Chet Baker, Stan Getz, Dizzy Gillespie, and Hampton Hawes.

Starting in the late 1980s, he became a bigger part of the avant-garde jazz scene when he played regularly at the Knitting Factory, recorded with singer Laurie Anderson, and began a long association with John Zorn.
