The CWA World Heavyweight Championship was a professional wrestling world heavyweight championship and the top title of the German professional wrestling promotion Internationalen Berufsringer Verbandes (IBV), later renamed the Catch Wrestling Association (CWA) in the title's honour. The title was created on August 2, 1977 and deactivated on December 4, 1999. The championship was contested under 15 three-minute rounds. It was replaced by the European Wrestling Promotion (EWP) World Heavyweight Championship when that organisation was founded in 2000 to replace the CWA.
It was originally claimed that the championship was sanctioned by a fictitious Canadian Wrestling Association and that it had previous lineage in North America. The title changed hands in four countries South Africa, Austria, the United States, and Germany and three continents - Africa, Europe, and North America.
