Neal Paul Hefti (October 29, 1922 – October 11, 2008) was an American jazz trumpeter, composer, and arranger. He wrote music for The Odd Couple movie and TV series and for the Batman TV series.
He began arranging professionally in his teens, when he wrote charts for Nat Towles. He became a prominent composer and arranger while playing trumpet for Woody Herman; while working for Herman he provided arrangements for "Woodchopper's Ball" and "Blowin' Up a Storm" and composed "The Good Earth" and "Wild Root". After leaving Herman's band in 1946, Hefti concentrated on arranging and composing, although he occasionally led his own bands.
