When Worlds Collide was a professional wrestling pay-per-view that took place on November 6, 1994 from the Los Angeles Memorial Sports Arena in Los Angeles, California. It was presented by the Mexican lucha libre company Asistencia Asesoría y Administración and promoted in conjunction with World Championship Wrestling. WCW Executive Vice-President Eric Bischoff had helped AAA secure a show on American pay-per-view and produced a show that received generally favorable reviews.

The show was broadcast in both English and Spanish. Chris Cruise and Mike Tenay called the action in English, while Arturo Rivera and Andrés Maroñas handled the Spanish announcing. This event also marked Tenay's first commentating role in professional wrestling.
