Ken Smith Basses is a boutique bass guitar manufacturer founded by Ken Smith in New York in the late 1970s, with production based in Perkasie, Pennsylvania. Before launching the company, Smith worked as a professional double bassist and electric bass player in New York City, where he built a reputation for repairing and modifying instruments for other musicians. The brand is credited with helping popularize several features now common in high-end electric basses, including through-neck construction and tapered core strings.

The company produces handmade electric basses in 4, 5, 6, and 7-string configurations, with model lines including the BSR (Bolt-on and neck-through variants), the Burner, and the Tiger Elite Series. Ken Smith Basses also manufactures its own line of bass strings, notably the Taper Core sets, and builds upright double basses. Wood selection is done in-house from a stock of aged tonewoods, and each instrument receives a final setup from Smith himself.

The brand is closely associated with jazz, fusion, and session bass playing. Notable players who have been connected with Ken Smith instruments include Anthony Jackson, John Patitucci, Stanley Clarke, Marcus Miller, Felix Pastorius, Hadrien Feraud, and Freddie Washington.
