Elton Dean (28 October 1945 – 8 February 2006) was an English jazz musician who performed on alto saxophone, saxello (a variant of the soprano saxophone) and occasionally keyboards.

Dean was born in Nottingham, England, moving to Tooting, London, soon after his birth. From 1966 to 1967, Dean was a member of the band Bluesology, led by Long John Baldry. The band’s pianist, Reginald Dwight, afterward combined Dean’s and Baldry’s first names for his own stage name, Elton John. This fact is noted in the 2019 film Rocketman, a biopic of the life and career of Elton John, where Dean is portrayed by Evan Walsh.
