Don Caballero is an American math rock group from Pittsburgh, Pennsylvania, United States. The group took their name from the character Guy Caballero, portrayed by Joe Flaherty, on the sketch comedy show Second City Television. In SCTV's parody of the film The Godfather, Guy Caballero is called "Don Caballero".
Don Caballero (affectionately called "Don Cab" or "The Don" by fans) formed in the summer of 1991, released five albums on Touch and Go Records between 1993 and 2000, then disbanded in November 2000. Drummer Damon Che recruited new personnel for a reconstituted Don Caballero in 2003 which has released two albums, World Class Listening Problem and Punkgasm on Relapse Records.
