SummerSlam (2012) was a professional wrestling pay-per-view (PPV) event produced by WWE that took place on August 19, 2012 at Staples Center in Los Angeles, California. It was the twenty-fifth annual SummerSlam, and the fourth consecutive one to be held at Staples Center.

The professional wrestling matches at SummerSlam featured professional wrestlers performing as characters in scripted events pre-determined by the hosting promotion, WWE. Storylines between the characters played out on WWE's primary television programs, Raw and SmackDown.

The most highly promoted match, billed as "The Perfect Storm", on the card saw Triple H facing of against Brock Lesnar. On the April 30, 2012 episode of Raw, Lesnar attempted to renegotiate his contract with General Manager John Laurinaitis. Triple H (in his corporate role as Chief Operations Officer) intervened, and declared that the contract Lesnar had agreed to upon re-signing with WWE was still valid and thus Lesnar could not add any other clauses to it. This led to a brawl between Lesnar and Triple H resulting in the latter having his arm broken by Lesnar via the Kimura armbar. Triple H returned at No Way Out, not only addressing Lesnar and the lawsuits brought against WWE, but also challenging him at SummerSlam, in exchange for his dropping the lawsuits that his legal representative, Paul Heyman, made against WWE and Triple H. On the June 18 episode of Raw, Heyman made an appearance, rejecting Triple H's challenge on behalf of Lesnar. After further goading from Heyman, Triple H attacked him. Meanwhile, it was announced that Lesnar would respond to Triple H's challenge on the July 2 edition of Raw; however, at the event it was announced that he will instead return at the 1000th episode of Raw on July 23. On Raw 1000, Heyman again declined the challenge, but after Triple H's wife Stephanie McMahon slapped him (due to making remarks about their children), Heyman accepted on behalf of Lesnar. Then on the August 6, 2012 episode of Raw, Shawn Michaels made an appearance to announce he'll be in Triple H's corner at SummerSlam. However, Michaels would not make it to SummerSlam after Lesnar used a Kimura lock to break his arm on the August 13, 2012 episode of Raw.
