Sam Coslow (December 27, 1902 - April 2, 1982) was an American songwriter, singer and film producer. Coslow was born in New York City. He began writing songs as a teenager. He contributed songs to Broadway revues, formed the music publishing company Spier and Coslow in 1928 and made a number of vocal recordings.

With the explosion of film musicals in the late 1920s, Hollywood attracted a number of ambitious young songwriters and Coslow joined the exodus in 1929. Coslow and his partner Larry Spier sold their publishing business to Paramount Pictures and Coslow became a Paramount songwriter. He formed a successful partnership with composer Arthur Johnston and together they provided the scores for a number of films including Bing Crosby vehicles. Coslow became a film producer in the 1940s and won the Academy Award for Best Short Film for his production Heavenly Music in 1943. He died in New York City.
