Jesús Velázquez Quintero (February 22, 1910 – May 26, 1972), better known under the ring names El Murciélago Enmascarado and Murciélago Velázquez, was a Mexican luchador (or professional wrestler). Velázquez was the fourth wrestler in Mexico to wear a wrestling mask and the second Mexican to work as an enmascarado ("masked wrestler") in the history of lucha libre. He became the first wrestler in Mexico to be forced to unmask, losing a Lucha de Apuestas (or "Bet match") to Octavio Gaona, creating the most prestigious match type in lucha libre. He once held the Mexican National Middleweight Championship and after his retirement was the head of the Mexico City boxing and wrestling commission for a while.
