The CMLL 66th Anniversary Show was a professional wrestling major show event produced by Consejo Mundial de Lucha Libre (CMLL) that took place on September 24, 1999 in Arena México, Mexico City, Mexico. The show consisted of seven matches, with the main event being a Parejas Suicidas match where the losing team would be forced to wrestle against each other in a Lucha de Apuestas, mask vs. mask match, immediately after the tag team match. Atlantis and Villaño III defeated Mr. Niebla and Shocker, forcing Mr. Niebla and Shocker to wrestle each other in the final match of the night. The show also featured three Six-man tag team matches, a four against three handicap match and a tag team match.

The event commemorated the 66th anniversary of CMLL, the oldest professional wrestling promotion in the world. The Anniversary show is CMLL's biggest show of the year, their Super Bowl event.

The 1999 CMLL Anniversary Shows commemorated the 66th anniversary of the Mexican professional wrestling company Consejo Mundial de Lucha Libre (Spanish for "World Wrestling Council"; CMLL) holding their first show on September 22, 1933 by promoter and founder Salvador Lutteroth. CMLL, originally known as Empresa Mexicana de Lucha Libre ("Mexican Wrestling Company"; EMLL) it would change its name to Consejo Mundial de Lucha Libre in 1992 to signal their departure from the National Wrestling Alliance. With the sales of the Jim Crockett Promotions to Ted Turner in 1988 CMLL became the oldest, still-operating wrestling promotion in the world. Over the years CMLL has on occasion held multiple shows to celebrate their anniversary but since 1977 the company has only held one annual show, which is considered the biggest show of the year, CMLL's equivalent of WWE's WrestleMania or their Super Bowl event. CMLL has held their Anniversary show at Arena México in Mexico City, Mexico since 1956, the year the building was completed, over time Arena México earned the nickname "The Cathedral of Lucha Libre" due to it hosting most of CMLL's major events since the building was completed. Traditionally CMLL holds their major events on Friday Nights, replacing their regularly scheduled Super Viernes show.
