Kenny Ball (born Kenneth Daniel Ball, 22 May 1930, Ilford, Essex, England) is an English jazz musician, best known as the lead trumpet player in Kenny Ball and his Jazzmen.

Ball began his career as a semi-professional sideman in bands, whilst also working as a salesman and for an advertising agency. He played the trumpet in bands led by Charlie Galbraith, Sid Phillips, Eric Delaney and Terry Lightfoot before forming his own trad jazz band in 1958. His dixieland band was at the forefront of the early 1960s UK jazz revival.

In 1971 their recording of Cole Porter's 'Samantha' became a hit, and in March 1962, Kenny Ball and His Jazzmen reached both #2 on the U.S. Billboard Hot 100 chart, and the UK Singles Chart, with "Midnight in Moscow". The record sold over one million copies, earning gold disc status. Further hits ensued, including a version of 'March of the Siamese Children' from 'The King and I', which topped the pop music magazine, New Musical Express chart in March that year, and such was their popularity in the UK that Ball was featured, alongside Cliff Richard, Brenda Lee, Joe Brown, Craig Douglas and Frank Ifield, on the cover of the New Musical Express in July 1962, although in the U.S. they remained a 'one-hit wonder'.
