The MWA World Heavyweight Championship was an American professional wrestling world heavyweight championship in the Kansas City, Kansas-based Midwest Wrestling Association (MWA). It was the direct predecessor of the National Wrestling Alliance (NWA) World Heavyweight Championship, and a successor of sorts to the early world heavyweight championships. The title was created in 1940, and first held by Bobby Bruns that January. At an unknown period, Brown won the Kansas Heavyweight Champion and had a match against 4-time World Heavyweight Champion Ed "Strangler" Lewis.
On November 8, 1933, Brown defeated Chief Chewchki in St. Louis, Missouri in 7 minutes.
