Kenneth Lucien Hanna (July 8, 1921 - December 10, 1982) was an American jazz trumpeter, arranger, composer, and bandleader, best known for his work with Stan Kenton.

He wrote almost 40 forward thinking compositions and arrangements between 1942 and 1951. He returned to the Kenton writing staff in the late 1960s, contributing over 70 more titles between 1968 and 1977.
