The Torneo Gran Alternativa (2006) (Spanish for "Great Alternative Tournament") was a professional wrestling tournament held by the Mexican professional wrestling promotion Consejo Mundial de Lucha Libre (CMLL; Spanish for "World Wrestling Council"). The tournament was held on June 2, 2006, in Mexico City, Mexico at CMLL's main venue, Arena México. The Gran Alternativa tournament features tag teams composed of a rookie, or novato, and a veteran wrestler for an elimination tournament. The idea is to feature the novato wrestlers higher on the card that they usually work and help elevate one or more up the ranks. Since it is a professional wrestling tournament, it is not won or lost competitively but instead by the decisions of the bookers of a wrestling promotion that is not publicized prior to the shows to maintain the illusion that professional wrestling is a competitive sport.
The eight-team tournament was won by rookie Misterioso Jr. and Perro Aguayo Jr. by defeating the teams of Máscara Purpura (rookie) and Lizmark Jr., Hombre Sin Nombre (rookie) and Héctor Garza and finally the team of Nitro (rookie) and Último Guerrero. This was Misterioso Jr.'s third Gran Alternativa tournament as a rookie, and Perro Aguayo Jr.'s only Gran Alternativa win of his career.
