Clemente Marcelino Valencia Nájera (17 July 1968 – 11 October 2011) was a Mexican luchador enmascarado, or masked professional wrestler, better known by the ring name Doctor X, under which he worked for the Mexican professional wrestling promotion Consejo Mundial de Lucha Libre (CMLL) for most of his career, winning the Mexican National Welterweight Championship and the Mexican National Trios Championship, teaming with Sangre Azteca and Nitro.

Doctor X was a member of Pandilla Guerreras and co-leader of Los Guerreros Tuareg. In August 2011, he quit CMLL and joined Perros del Mal Producciones under the more extreme ring name Doctor X-Treme. He had previously worked as Dr. O'Borman Jr., a name he licensed from the original Dr. O'Borman.

Throughout his career, Doctor X's real name and personal life was not a matter of public record, as is often the case with masked wrestlers in Mexico. He was killed while trying to break up a fight.
