The Memphis Wrestling Southern Heavyweight Championship is a major professional wrestling title in the Memphis Wrestling promotion. The title is part of a long lineage that is best known while the title was named the AWA Southern Heavyweight Championship for Continental Wrestling Association during the 1970s and 1980s.
It was made when the NWA Southern Junior Heavyweight Championship, in use since 1939, was renamed the NWA Southern Heavyweight Championship (Memphis version) in 1974. The title's name changed again in 1978, when it was renamed the AWA Southern Heavyweight Championship due to a partnership with the American Wrestling Association. It was also called the Mid-Southern Heavyweight Championship in Pro Wrestling Illustrated and its sister publications, in order for this title to not be confused with Championship Wrestling from Florida's version of the title.
The title was revived in the United States Wrestling Association from 1989 until 1997 when the USWA closed. It was known as the USWA Southern Heavyweight Championship and later simply the USWA Heavyweight Championship during that time; however, unlike the previous Southern title in Memphis, this one played a secondary role to the USWA Unified World Heavyweight Championship. It was revived again in Memphis Championship Wrestling as the MCW Southern Heavyweight Championship in 2000 and 2001. It was later revived and renamed in 2004 for use in Memphis Wrestling, where it is still defended today.
