Charles "Ike" Isaacs (March 28, 1923 – February 27, 1981) was an American jazz double bassist from Greater Cleveland.
Born in Akron, Ohio, Isaacs played trumpet and tuba as a child before settling on bass.
He led a band locally in Ohio in 1956, then played for two years in the trio of Carmen McRae, whom he married late in the decade.
He worked with Lambert, Hendricks and Ross, then with Count Basie (1962), Gloria Lynne (1962–64), and Erroll Garner (1966–70), as well as with his own small groups.
On this recording he plays in a trio with Jack Wilson on piano and Jimmie Smith on drums.
