Al Cohn (November 24, 1925 – February 15, 1988) was an American jazz saxophonist and arranger and composer.

Alvin Gilbert Cohn was born in Brooklyn, New York. He was initially known in the 1940s for playing in Woody Herman's Second Herd as one of the Four Brothers, along with Zoot Sims, Stan Getz, and Serge Chaloff. Unlike the better known tenors Sims and Getz, Cohn contributed arrangements to the Herman band. Cohn had a reputation as a lyrical flowing soloist.
