Anthony John Archer (b. July 14, 1938, Dulwich, London) is an English jazz double-bassist.
Archer studied cello as a schoolboy before settling on upright bass. He joined Don Rendell's group in 1961, then with Roy Budd and Eddie Thompson before beginning work with Tony Lee, with whom he would collaborate for many years, particularly at Ronnie Scott's Jazz Club. He later played with Brian Lemon, Sandy Brown, Harold McNair, John Dankworth, and in the Best of British Jazz group with Kenny Baker and Don Lusher. Archer continued to work with Lee nearly up until Lee's death in 2004.
