Malick Seck was a judoka from Senegal who competed internationally during the early 1990s. Seck was selected to participate in the lightweight event at the 1992 Barcelona Olympics. He lost his opening bout to Jeong Hun (KOR), who went on to win a bronze medal. Seck also then had an opportunity to win a bronze via the repêchage, but lost to Massimo Sulli (ITA) after earlier winning against Steve Corkin (NZL). His younger brother Adboul was also a judoka who competed in the half-heavyweight class at the 1996 Atlanta Olympics.
