Chester Conn (né Master Chester Cohn; April 14, 1894 in San Francisco, California – April 4, 1973 in Flushing, Queens) was an American composer of popular music and music publisher.^[1]

Chester was born to David Cohn and Minnie (née Newman; 1871–1946).^[2] At an early age, Chester was raised by his mother, who had become a widow sometime before 1900. In 1918, Cohn was working for Broadway Music Corp^{[lower-alpha 1]} in New York.^[3] In 1922, Cohn was working for Leo Feist, Inc., in its Chicago office.^[4] In 1937, Conn co-founded the New York music publishing of Bregman, Vocco & Conn, Inc. ("BVC"). The other name partners were Jack Bregman (né Joseph Bregman; 1901–1967) and Rocco Vocco (1887–1960). Chester Conn's only child, a son, Jack D. Conn (1926–1966), had been an executive at BVC. Given that Bregman, Vocco, and Jack Conn all predeceased Chester, Chester sold the firm in May 1967 to 20th Century Fox for 4.5 million dollars in cash.^[5]
