The St. Louis Wrestling Club was a professional wrestling promotion based in St. Louis, Missouri. It was owned and operated by Sam Muchnick. The promotion was a flagship member of the National Wrestling Alliance, and promoted primarily in the St. Louis area. It was colloquially referred to within the business as the "St. Louis office" of the NWA.
The St. Louis Wrestling Club as part of the National Wrestling Alliance recognized the NWA World Heavyweight Championship as their world title and the champion would frequently tour the St. Louis territory. Outside of the NWA World Heavyweight Championship the territory recognized or promoted the following titles at some point in time.
- NWA Missouri Heavyweight Championship
- NWA United States Heavyweight Championship (Central States version)
- NWA Central States Heavyweight Championship (1950–1972)
The Central States Heavyweight Title was the forerunner to the Missouri Heavyweight Championship. The title was created after a controversy on January 28, 1972 where Pat O'Connor defeated Harley Race for the Central States title. When promoters refused to recognize the title change and kept promoting Harley Race as the Central States champion Muchnick stopped recognizing the Central States title opting instead to create the Missouri Heavyweight Title instead.
