The 2013 Night of Champions was the seventh annual Night of Champions professional wrestling pay-per-view (PPV) event produced by WWE. It took place on September 15, 2013, at the Joe Louis Arena in Detroit, Michigan. This was WWE's last pay-per-view event to take place at the Joe Louis Arena before its closure in 2017 with future WWE events in Detroit held at the Little Caesars Arena. The theme of the event was that every championship promoted on WWE's main roster at the time was defended. The event received 175,000 buys, down from the last year's event of 189,000.

Nine matches were contested at the event, including one on the Kickoff pre-show. In the main event, Daniel Bryan defeated Randy Orton to win the WWE Championship. In other prominent matches, Rob Van Dam defeated World Heavyweight Champion Alberto Del Rio via disqualification thus Del Rio retained, and Curtis Axel and Paul Heyman defeated CM Punk in a No Disqualification Handicap Elimination match.
