Juicio Final 1990 (Spanish for "Final Justice") was a professional wrestling major show event produced by Empresa Mexicana de Lucha Libre (EMLL) that took place on December 14, 1990 in Arena Mexico, Mexico City, Mexico. It was the last major show produced by EMLL under that name as they were renamed Consejo Mundial de Lucha Libre (CMLL) a few months later.
The main event of Juicio Final was a three way, round-robin tournament between Octagón, Fuerza Guerrera and Huracán Ramírez II (not to be mistaken for the original Huracán Ramírez). The three men faced off against each other in singles matches until one man had scored two wins, eliminating him from the tournament. The remaining two wrestlers faced each other in a Lucha de Apuesta match where both men would put their masks on the line. Guerra defeated both Octagón and Ramírez, forcing those two men to wrestle for their masks in the main event. The final saw Octagón defeate Ramírez, earning the mask of Huracán Ramírez II. Following the match Ramírez unmasked and revealed that his real name was "Name" as per Lucha Libre traditions.
The event featured five professional wrestling matches with different wrestlers involved in pre-existing scripted feuds or storylines. Wrestlers portray either villains (referred to as Rudos in Mexico) or fan favorites (Técnicos in Mexico) as they compete in wrestling matches with pre-determined outcomes.
