Máscara Dorada (born November 3, 1988) is a Mexican luchador enmascarado currently signed to WWE under the ring name Gran Metalik, performing on the Raw and 205 Live brands, where is a former Cruiserweight Champion. He is best known for his decade long stint in Consejo Mundial de Lucha Libre (CMLL). Máscara Dorada's real name has not been officially documented, a tradition in Mexican Lucha Libre where masked wrestlers' real names often are not a matter of public record. The wrestler currently known as Máscara Dorada made his debut in 2005 and has worked under other names, but achieved most success as Máscara Dorada. His ring name is Spanish for "Golden Mask".

At one time, Máscara Dorada was a quadruple CMLL champion, holding the Mexican National Trios Championship, the CMLL World Trios Championship, the CMLL World Super Lightweight Championship and the CMLL World Welterweight Championship at the same time. He has held the CMLL World Welterweight Championship four times in total. After a decade of working for CMLL in his native Mexico, Dorada signed with the Japanese promotion New Japan Pro Wrestling (NJPW) in January 2015. After a year with NJPW, Dorada returned to CMLL in February 2016.

He made his in-ring debut in 2005, originally using the masked persona Plata II and later on would use the ring name Metallik where he held the local Occidente Welterweight Championship, but abandoned it when he was given the Máscara Dorada character. The "Máscara Dorada" was the first instance of a regular luchador being given a character based on a Mini-Estrella as he was introduced after CMLL introduced Mascarita Dorada in 2007.
