Miss USA 2012 was the 61st Miss USA pageant, held on June 3, 2012, at the PH Live in Las Vegas, Nevada and it was televised live on NBC. Alyssa Campanella of California crowned her successor Olivia Culpo of Rhode Island at the end of the event. This was Rhode Island's first Miss USA title. Culpo represented the United States at Miss Universe 2012 six months later and went on to win the Miss Universe title, becoming the eighth American to do so.

Miss USA is an American beauty pageant that has been held annually since 1952 to select the entrant from United States in the Miss Universe pageant. The Miss Universe Organization operated both pageants, as well as Miss Teen USA, until 2020, when the organization announced it was licensing operation of the Miss USA and Miss Teen USA pageants to Crystle Stewart, Miss USA for 2008 prior to her suspension in October 2022, thus returning the said pageants to the Miss Universe Organization.
