The NWA World Six-Man Tag Team Championship was a professional wrestling championship sanctioned by the National Wrestling Alliance (NWA) and originally promoted in Chicago as the NWA World Three-Man Tag Team Championship.
The NWA Mid-America territory based out of Tennessee re-introduced the title as the NWA Six-Man Tag Team Championship, promoting it from 1974 until 1981.
In 1984, another NWA territory Jim Crockett Promotions (JCP) brought the concept back, this time as the "NWA World Six-Man Tag Team Championship", which continued to be promoted by JCP's successor World Championship Wrestling until 1989.
The championship was briefly revived in February 1998 by Dennis Coralluzzo's NWA New Jersey territory, also known as Championship Wrestling America.
Because the championship was a professional wrestling championship, it was won or lost by the decision of the bookers of a wrestling promotion.
