The USWA Unified World Heavyweight Championship was a professional wrestling world heavyweight championship formed in 1988, which consisted of the WCWA World Heavyweight Championship from World Class Championship Wrestling and the AWA World Heavyweight Championship from the American Wrestling Association. The title was unified on December 13, 1988, when AWA World Champion Jerry Lawler defeated WCWA World Champion Kerry Von Erich in a unification match.

The AWA World Heavyweight Championship was a professional wrestling world heavyweight championship and the highest ranked championship in the defunct American Wrestling Association (AWA). All AWA trademarks, including the AWA World Heavyweight Championship, are now owned by WWE. The championship was generally contested in professional wrestling matches, in which participants execute worked finishes rather than contend in direct competition.
