Booker Telleferro Ervin II (October 31, 1930 – August 31, 1970) was an American tenor saxophoneplayer. His tenor playing was characterised by a strong, tough sound and blues/gospel phrasing. He is remembered for his association with bassist Charles Mingus.

Ervin was born in Denison, Texas, United States. He first learned to play trombone at a young age from his father, who played the instrument with Buddy Tate. After leaving school, Ervin joined the United States Air Force, stationed in Okinawa, Japan, during which time he taught himself tenor saxophone. After completing his service in 1953, he studied at Berklee College of Music in Boston, Massachusetts. Moving to Tulsa in 1954, he played with the band of Ernie Fields.

Ervin died of kidney disease in New York City in 1970, aged 39. Most biographical accounts of Ervin’s death give an incorrect date. His gravestone in The National Cemetery, East Farmingdale, New York, clearly shows the date as August 31, 1970.
