The Bojayá massacre () was a massacre that occurred on May 2, 2002 in the Colombian town of Bojayá (with its urban centre also referred to as Bellavista), in Chocó department. FARC guerrillas seized the town in an attempt to take control of the Atrato River region from AUC paramilitaries, in the process killing approximately 119 civilians in an apparently indiscriminate attack with an improvised homemade mortar assembled with gas cylinders parts (known in Spanish as pipeta or Cilindro bomba).
