The 2014 Night of Champions was the eighth annual Night of Champions professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It took place on September 21, 2014, at the Bridgestone Arena in Nashville, Tennessee, and was the first Night of Champions event to livestream on the WWE Network, which launched in February. The theme of the event was that every championship promoted on WWE's main roster at the time was defended.

Eight matches were contested at the event. Of the five championships contested, three changed hands. The main event saw John Cena defeat Brock Lesnar by disqualification, after Money in the Bank holder Seth Rollins interfered in the match by attacking Cena, thus Lesnar retained his WWE World Heavyweight Championship. The event also saw AJ Lee defeat defending champion Paige and Nikki Bella to win her record-tying third WWE Divas Championship. This was also the last WWE PPV to date to feature Justin Roberts as a ring announcer as he would be released the following month. The event had 48,000 buys (excluding WWE Network views). The previous year's drew 175,000 buys.
