The NWA United States Heavyweight Championship is a name used for several secondary championships used by various National Wrestling Alliance (NWA) members since 1953. At least twelve different versions of the NWA United States Heavyweight Championships have been promoted in various regions across the United States. The NWA's bylaws allowed any NWA member, also known as an NWA territory, to create and control their own version of the NWA United States Heavyweight Championship. The most well known version was the Mid-Atlantic Wrestling version, which later became the WCW United States Heavyweight Championship, and is still active as the WWE United States Championship.
