The Torneo Gran Alternativa (2013) was a professional wrestling tournament event produced by Consejo Mundial de Lucha Libre (CMLL) that took place from April 12 until April 26, 2013 over the course of two CMLL Super Viernes shows, with the finals on the Arena Mexico 57th Anniversary Show. The Torneo Gran Alternativa (Spanish for "the Great Alternative tournament) concept sees a Novato or rookie team up with an experienced wrestler for a tag team tournament. The rookie winner is often elevated up the ranks of CMLL as a result of winning the tournament, but there is no specific "prize" for winning the tournament. The tournament was won by rookie Boby Zavala and veteran Rey Escorpión, Escorpión's second tournament win overall.

The tournament features 15 professional wrestling matches with different wrestlers teaming up, some of which may be involved in pre-existing scripted feuds or storylines while others are simply paired up for the tournament. Wrestlers portray either villains (referred to as Rudos in Mexico) or fan favorites (Técnicos in Mexico) as they compete in wrestling matches with pre-determined outcomes. The tournament format follows CMLL's traditional tournament formats, with two qualifying blocks of eight teams that compete on the first and second week of the tournament and a final match between the two block winners. The qualifying blocks were one-fall matches while the tournament finals will be a best two-out-of-three falls tag team match. Each qualifying block started with all 8 Novatos competing in a "seeding" battle royal to determine the brackets for the block.
