Infierno en el Ring 2012 (Spanish for "Inferno in the Ring") was an annual professional wrestling major event produced by Consejo Mundial de Lucha Libre (CMLL), which took place on June 29, 2012 in Arena México, Mexico City, Mexico. The 2012 Infierno en el Ring replaced CMLL's regularly scheduled Friday night Super Viernes show. The 2012 Infierno en el Ring was the fourth show under that name, the 14th time CMLL have promoted an Infierno en el Ring cage match and the first time it featured women competing in the main event. The main event of the show was the eponymous Infierno en el Ring match that CMLL traditionally has traditionally held approximately once a year and which has headlined its own specific show since 2008. The Infierno en el Ring match is a multi-person Steel Cage match contested under Lucha de Apuesta, or bet match, rules which means that the loser of the match would be forced to unmask or have their hair shaved off per Lucha Libre traditions. At the 2012 event 10 women participated, risking either their mask, (La Seductora and Goya Kong) or their hair (La Amapola, Estrellita, Dark Angel, Lady Apache, Tiffany, Marcela, Dalys la Caribeña and Princesa Blanca).
