Charnett Moffett (born 10 June 1967) is an American jazz musician who plays piccolo bass, double bass and bass guitar.
Moffett's given name was created as a combination of that of his father (Charles Moffett, the jazz drummer) and that of Ornette Coleman (the jazz saxophonist). As a teenager Moffett played in his father's band, but by the mid-1980s he had begun to create a reputation playing with Wynton Marsalis and Branford Marsalis. This led to a career as a free-lance bassist, and he has performed and recorded with a long string of musicians, including Stanley Jordan, Harry Connick, Jr., Ornette Coleman, McCoy Tyner, Kenny Garrett, Mulgrew Miller, Courtney Pine, Arturo Sandoval, Lew Soloff and Sonny Sharrock. He has also played and recorded as a leader. He is a former member of the Manhattan Jazz Quintet. He is currently a member of Melody Gardot's band.
