The CMLL 65th Anniversary Show was a professional wrestling major show event produced by Consejo Mundial de Lucha Libre (CMLL) in 1998. Different sources identify different shows in September as the actual Anniversary Show, either on September 11 or September 18, or possibly both as CMLL has held multiple shows to commemorate their anniversary in the past. Both shows took place in Arena Mexico in Mexico City, Mexico. The September 11th show consisted of five matches in total, with one of the featured bouts being a Best two-out-of-three falls Lucha de Apuesta mask vs. mask match between Último Guerrero and Mr. Águila, the first Luchas de Apuestas match of Último Guerrero's career.

José Gutiérrez Hernández, better known by his ring name Último Guerrero, is a Mexican luchador, who works for Consejo Mundial de Lucha Libre (CMLL). He is not related to the lucha libre legend Gory Guerrero or any of his children; "Guerrero" in this case is the Spanish word for warrior and not the surname of the character. On September 19, 2014, Último Guerrero lost a Lucha de Apuestas match to Atlantis, after which he was forced to unmask and reveal his birth name.
