Neal Hefti (October 29, 1922 – October 11, 2008) was an American jazz trumpeter, composer, songwriter, and arranger. He composed the theme music for the Batman television series of the 1960s, and scored the 1968 film The Odd Couple and the subsequent TV series also titled The Odd Couple.

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 new 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. He is especially known for his charts for Count Basie such as "Li'l Darlin'" and "Cute".
