The NWA Mid-Atlantic Heavyweight Championship, originally known as the NWA Eastern States Heavyweight Championship, was a professional wrestling championship promoted in Jim Crockett Promotions (JCP), a territory-promotion governed by the National Wrestling Alliance (NWA).

[Note 2] It was announced that the Missouri Mauler had defeated the defending champion Pat O'Connor in New York City to win the title; this title change was fictitious and a storyline to introduce the championship to the promotion; nevertheless, O'Connor's reign is denoted as the first official reign.

At the time of this change, Jerry Brisco was in his fourth reign as the NWA Eastern Heavyweight Champion, and as a result of never losing the title, he was recognized as the first NWA Mid-Atlantic Heavyweight Champion.

Fifteen of those reigns occurred while the title was called the "NWA Eastern Heavyweight Championship" while 46 reigns occurred under the "NWA Mid-Atlantic Heavyweight Championship" name.

Ken Patera's second reign was the longest in the title's history at 334 days.
