The 2015 Payback was the third annual Payback professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It took place on May 17, 2015, at the Royal Farms Arena in Baltimore, Maryland and was the first Payback held outside of the Chicago suburb of Rosemont, Illinois. The theme of the event was wrestlers seeking payback against their opponents.

Nine matches were contested at the event, including two on the Kickoff pre-show. In the main event, Seth Rollins defeated Roman Reigns, Dean Ambrose, and Randy Orton in a fatal four-way match to retain the WWE World Heavyweight Championship. In other prominent matches, The New Day (Big E and Kofi Kingston) defeated Cesaro and Tyson Kidd in a two out of three falls match to retain the WWE Tag Team Championship, Bray Wyatt defeated Ryback, and John Cena defeated Rusev in an "I Quit" match to retain the WWE United States Championship. The event sold 54,000 buys (excluding WWE Network views), down from the previous year's 67,000 buys.
