George Masso (born November 17, 1926), born in Cranston, Rhode Island, is an American jazz trombonist, bandleader, vibraphonist and composer specializing in swing and Dixieland styles. Masso is most notable for his work from 1948-1950 in the Jimmy Dorsey band. Finding the life of a professional jazz musician financially difficult, Masso quit performing following his work with Dorsey but returned years later in a 1973 recording and performed with Bobby Hackett and Benny Goodman. In the late 1980s and early 1990s, Masso did several recordings with Barbara Lea, Bob Haggart and Yank Lawson.
