The SCW World Heavyweight Championship briefly served as the top singles title in Southwest Championship Wrestling for a few months in 1983. The title was established in response to SCW landing a television show on the USA Network in late-1982, but after USA controversially canceled Southwest Championship Wrestling a few months later and turned its TV time over to WWF All American Wrestling, the title was forgotten and eventually abandoned.
