In WWE (formerly known as the World Wide Wrestling Federation/WWWF and World Wrestling Federation/WWF), the term Triple Crown Champion has traditionally been used to describe a wrestler who has won the WWE Championship, the Intercontinental Championship, and the (now defunct) World Tag Team Championship. For a span of nearly eighteen years, from 1979 up through 1997, these were the only three championships of the company, and a wrestler who won all three championships (not necessarily concurrently) was considered a "Triple Crown Champion". Until the 1990s, the accomplishment was extremely rare, with Pedro Morales remaining the sole Triple Crown winner for more than a decade.
