Jack Six (July 26, 1930 – March 14, 2015) was an American jazz double-bassist and composer.
Six was born in Danville, Illinois, and initially learned trumpet as a teenager before switching to bass.
In the first half of the 1960s he played with Don Elliott, Jimmy Raney, Kenny Davern, The Dukes of Dixieland, and Herbie Mann; he continued working with Davern alongside Dick Wellstood as the house band for the Ferryboat, a club in Brielle, New Jersey.
He directed musical events at a casino in Atlantic City in the early 1980s and recorded with Susannah McCorkle and Jack Reilly; later that decade he returned to Brubeck's ensemble, remaining with him until he retired in the 1990s.
