Lucien "Sonny" Banks (June 29, 1940 – May 13, 1965) was a mid-20th Century American boxer who is primarily remembered for being the first boxer to ever knock down Cassius Clay (later "Muhammad Ali") in a professional match. In the early 1960s Banks was regarded in the sport as rising prospect known for a lightning fast left hook, but his career was cut short when he died from injuries sustained in the ring in 1965.

Banks was from Lee County in north east Mississippi. He was born in the farming community at Birmingham Ridge, about halfway between Tupelo and Saltillo.^[1]

He fought Clay on 10 February 1962 in New York, and knocked him down for a count, although he went on to lose the match.^[2]

Banks died on 13 May 1965 at the age of 24 from a head injury sustained three days earlier in a 9-round bout against Leotis Martin.
