The Leyenda de Azul is a lucha libre tournament held seven times by the Mexican professional wrestling promotion Consejo Mundial de Lucha Libre (CMLL) between 2000 and 2008 and again in 2011 and 2012. The tournament honors Blue Demon, or Demonio Azul as he's sometimes referred to. The tournament is not nearly as prestigious as CMLL's annual Leyenda de Plata tournament. The winner is given a plaque with a Blue Demon mask on it and a championship belt featuring Blue Demon as well. All tournaments have taken place in Arena México in Mexico City and all were held on Fridays during CMLL's Super Viernes show. In 2009 Blue Demon Jr. threatened to take legal action against CMLL on behalf of the National Wrestling Alliance over CMLL's use of three NWA branded championships. While CMLL did not publicly respond to the threat they dropped the tournament from their schedule for two years. In July 2011, CMLL, still not on good terms with Blue Demon Jr., announced the return of the tournament. The tournament would instead be endorsed by Blue Demon's biological son and Blue Demon Jr.'s adopted brother, El Hijo de Blue Demon.
