The Grand Slam Championship is an accomplishment in professional wrestling. It is a distinction made to a professional wrestler who has won four specific championships in WWE or Total Nonstop Action Wrestling. The four titles typically feature three levels of singles championships and a tag team championship. These singles championships include a World Heavyweight,Secondary, and Tertiary championship. As a result, a Grand Slam Champion is also inherently a Triple Crown Champion, which consists of only two levels of singles titles and a tag team title(a tertiary championship is not necessary for a Triple Crown).
