Juicio Final (1991) (Spanish for "Final Justice") was a professional wrestling major show event produced by Consejo Mundial de Lucha Libre (CMLL) that took place on December 13, 1991 in Arena México, Mexico City, Mexico. Documentation foronly three matches on the show have been found, the main event and two Six-man "Lucha Libre rules" tag team match undercard matches.

The main event of Juicio Final was a Lucha de Apuestas, mask vs. mask match between Máscara Año 2000 and Aníbal. The match saw Máscara Año 2000 defeat Aníbal, forcing him to unmask and reveal his real name, Carlos Ignacio Carrillo Contreras, after the match per Lucha libre traditions. The first of two six-man tag team matches was built around the feud between Kato Kung Lee and Kung Fu as they each captained a team for the match. Kato Kung Lee teamed with Mexican National Tag Team Champions Misterioso and Volador to defeat Kung Fu, Blue Panther and Herodes. The other six man tag team match saw three of CMLL's top tecnicos in Atlantis, Dos Caras and Konnan, defeat one of CMLL's top rudo trios Los Infernales (El Satánico, MS-1 and Pirata Morgan).
