The 2014 SummerSlam was the 27th annual SummerSlam professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It took place on August 17, 2014, at Staples Center in Los Angeles, California for the sixth and final consecutive year. This was also the first SummerSlam event to air on WWE's livestreaming service, the WWE Network, which launched in February. It was also the first WWE pay-per-view to incorporate the new WWE logo but it would not be used on air and on the turnbuckle pads until the next night on Raw. This would also be the last WWE pay-per-view to feature the championships with the scratch logo as all were updated with the new logo also on the following night's Raw.

SummerSlam is a professional wrestling event, produced annually since 1988 by the world's largest professional wrestling promotion, WWE. Dubbed "The Biggest Party of the Summer", it is considered WWE's second biggest event of the year behind their flagship event, WrestleMania. It is also considered one of the company's five biggest events of the year, along with WrestleMania, Royal Rumble, Survivor Series, and Money in the Bank, referred to as the "Big Five". The event has been broadcast on pay-per-view (PPV) since the inaugural 1988 event and via livestreaming since the 2014 event.
