Traidor, inconfeso y mártir (English: Treacherous, Unconfessed, and Martyr) is an 1849 Spanish three-act play by José Zorrilla, who also wrote Don Juan Tenorio. It is a historical drama in the Spanish Romantic style and is loosely based on a historical incident in which a Spanish baker, Gabriel de Espinosa, was prosecuted as an imposter for the missing King Sebastian of Portugal. The play's setting is less elaborate than that of many other plays written during the Romantic period, primarily because the author was interested in the character development of the protagonist Gabriel Espinoza.
