The WWE Universal Championship is a men's professional wrestling world heavyweight championship created and promoted by the American promotion WWE, defended on the SmackDown brand division. Since April 2022, the title has been jointly held and defended with the WWE Championship as the Undisputed WWE Universal Championship, but both titles have maintained their individual lineages. It is one of three world titles in WWE, alongside its companion WWE Championship on SmackDown, and the World Heavyweight Championship on Raw. The current champion is Cody Rhodes, who is in his first reign. He won the undisputed championship by defeating previous champion Roman Reigns in a Bloodline Rules match at WrestleMania XL Night 2 on April 7, 2024.
