Jack Sharpe (19 August 1930 – 4 November 1994) was an English jazz saxophonist and bandleader, primarily active in the London jazz scene. He began playing the tenor saxophone at the age of eighteen and soon collaborated with notable musicians such as Vic Lewis and Teddy Foster in the early 1950s. Sharpe freelanced in the London area but temporarily left the music scene in 1953 to work as a taxi driver. He returned to music in 1954, playing with Dizzy Reece, and later joined Tubby Hayes's band from 1955 to 1956. After 1957, he performed with Mike Senn in The Downbeaters and continued to work with Hayes. In 1958, he led his own sextet and also engaged in promotion and booking for other musicians.

In the early 1970s, Sharpe managed a nightclub, leading the house band on weekends. Around 1975, he intermittently left music to drive a cab but made a significant return to the jazz scene in 1985. During this period, he played with Alan Branscombe and led a Tubby Hayes tribute band, which recorded three albums, including "Catalyst: A Tribute to Tubby Hayes" in 1987 and "Roarin'" in 1989. Sharpe's contributions to jazz, particularly in London, left a lasting impact on the genre.
