Major Harris III (February 9, 1947^[1] – November 9, 2012)^[2] was an American R&B singer, associated with the Philadelphia soul sound and the Delfonics (early 1970s–1974). His biggest hit as a solo artist was the 1975 single "Love Won't Let Me Wait".

Harris was born in Richmond, Virginia, United States.^[1] Early in his career, Harris sang with groups such as the Charmers, the Teenagers, the Jarmels,^[1] and Nat Turner Rebellion, which also featured his songwriting brother, Joseph B. Jefferson, and recorded a few solo 7" records on the Laurie and Okeh labels. In the early 1970s, he took over from Randy Cain as a member of the Delfonics; he quit the group to go solo in 1974.^[1] Signing with Atlantic Records, Harris scored a string of R&B hits in the United States, including the top ten single "Love Won't Let Me Wait",^[1] which peaked at #5 in the US Billboard Hot 100 chart and #37 in the UK Singles Chart in September 1975. Written by Bobby Eli and Vinnie Barrett, "Love Won't Let Me Wait" was awarded a gold disc by the R.I.A.A. on 25 June 1975.^[3]

In 1984, Harris recorded the LP I Believe in Love on Streetwave Records, the title track of the same name which did receive airplay that year on BBC Radio 1 from DJ Robbie Vincent. However, the album had limited success.

When his success as a soloist subsided, Harris returned to the Delfonics,^[1] and continued to tour with one of two touring ensembles that used the name in the 1990s and 2000s. Major was a cousin to the Philadelphia record producer and arranger, Norman Harris.^[4]

Harris died in a Richmond, Virginia, hospital from congestive heart and lung failure at the age of 65.^[2]
