Irving Herbert Pomeroy III (April 15, 1930 – August 11, 2007) was an American jazz trumpeter, teacher, and the founder of the MIT Festival Jazz Ensemble.

After high school, he studied music from 1950 to 1952 at the Schillinger House in Boston.

Remaining in Boston, he played with Charlie Parker for one week in 1953, then briefly with Charlie Mariano, before going on tour with Lionel Hampton and Stan Kenton. Back in Boston, he played with Serge Chaloff and was hired to teach at Schillinger after it had been renamed the Berklee School of Music.
