Jim Pepper (June 18, 1941 – February 10, 1992) was a Kaw Nation and American jazz saxophonist, composer, and singer of Muscogee Native American heritage.
He came to prominence in the late 1960s as a member of The Free Spirits, an early jazz-rock fusion group who first recorded his best-known song, "Witchi Tai-To." Pepper went on to a lengthy career in jazz, recording almost a dozen albums as a bandleader and appearing as sideman with the likes of drummer Paul Motian and pianist Mal Waldron, often incorporating elements of Native American music into his style.
