The World Wrestling Entertainment (WWE) Championship is a professional wrestling world championship in World Wrestling Entertainment. It is the original world title of WWE. Currently, it is the highest ranked championship on the SmackDown Brand.

The WWE Championship was originally known as the World Wide Wrestling Federation (WWWF) World Heavyweight Championship. Following the title's introduction in 1963, Buddy Rogers became the inaugural champion on April 29. The World Wide Wrestling Federation joined the National Wrestling Alliance in 1971 and was renamed the World Wrestling Federation in 1979. During this time, the title was referred to as the World Wrestling Federation (WWF) Heavyweight Championship. It became known as the WWF World Heavyweight Championship when the promotion left the NWA in 1983. The title began to be referred to as the WWF Championship in 1998.

Special custom belts have been created for at least four different champions:

• "Superstar" Billy Graham (red leather strap)
• The Ultimate Warrior (white, blue and purple leather straps)
• "Stone Cold" Steve Austin ("Smoking' Skull" belt)
• Edge ("Rated-R Superstar Spinner" belt)

A belt with an exceptionally long strap was created for André the Giant before Wrestle Mania III; however he never wore it as champion. Similarly, Edge had originally designed an entirely different custom belt than the "Rated R Spinner" design he used for his second reign, however the plans were scrapped due to time constraints. The "Spinner" belt's design has become the WWE Championship's primary design, having been used by John Cena, Edge, Rob Van Dam, Randy Orton and although the centerpiece no longer spins.
