Marshall Brown (1920 - 1983) was a jazz musician and educator. He played trombones and, less often, bass trumpet or euphonium.

Brown was little recorded, and devoted most of his career to education. He earned a music degree from New York University.

Brown received some attention for performing in a quartet with Pee Wee Russell in the early 1960's. While Russell was most often associated with dixieland or swing music, their quartet performed more adventurous, free jazz-oriented pieces, including songs by Ornette Coleman and John Coltrane.

Brown also perfomed or recorded with Ruby Braff and Beaver Harris and Lee Konitz
