The WCWA World Heavyweight Championship was a professional wrestling world heavyweight championship in World Class Championship Wrestling. The title was originally created in June 1966 as the Texas version of the NWA United States Heavyweight Championship before being renamed the NWA American Heavyweight Championship in May 1968. When WCCW pulled out of the NWA in 1986, the championship was renamed the World Class Wrestling Association World Heavyweight Championship. The title was unified by Jerry Lawler with the AWA World Heavyweight Championship in 1989 and continued as the USWA Unified World Heavyweight Championship. World Class returned in September 1990 when the organization withdrew from the United States Wrestling Association (USWA), but the promotion ceased operations three months
