Terry O'Quinn nasceu o 15 de julho de 1952 em Michigan, EUA. É ator, conhecido pelo seu trabalho em Lost (2004), O Padrasto (1987) e Rocketeer (1991). Foi casado com Lori O'Quinn.
Is one of the few cast members of Lost (2004) who did not have to
audition, because his former collaborator (from Alias: Codinome Perigo (2001)) J.J. Abrams thought of O'Quinn for the part of Locke before the actor was even offered it.
