Irving Gifford Fine (December 3, 1914 – August 23, 1962) was an American composer. Fine's work assimilated neoclassical, romantic, and serial elements. Composer Virgil Thomson described Fine's "unusual melodic grace" while Aaron Copland noted the "elegance, style, finish and...convincing continuity" of Fine's music.
Fine was a member of a close-knit group of Boston composers in the mid-20th century who were sometimes called the "Boston Six" or "Boston School." Other members of the Boston School included Arthur Berger, Leonard Bernstein, Aaron Copland, Lukas Foss, and Harold Shapero.
