Miss Teen USA 2015 was the 33rd Miss Teen USA pageant. It was held at the Atlantis Paradise Island in Nassau, The Bahamas on August 22, 2015, and was hosted by Miss USA 2013 Erin Brady and television writer Nick Teplitz. All fifty states and District of Columbia competed. K. Lee Graham of South Carolina crowned her successor Katherine Haik of Louisiana at the end of the event.

Miss Teen USA is a beauty pageant that has been run since 1983 by the Miss Universe Organization for girls aged 14–19. Unlike its sister pageants Miss Universe, which currently broadcasts on JKN18 and Miss USA, this pageant is webcast on the Miss Teen USA website and simulcast on mobile devices and video game consoles. The Miss Universe Organization previously operated Miss Teen USA, as well as Miss USA, until 2020 when the rights to produce both pageants were licensed to Miss USA 2008 Crystle Stewart prior to her suspension in October 2022, thus returning the said pageants to the Miss Universe Organization. The parent company of all three pageants and the Miss Universe organization remains the same under the licensing agreement: JKN Metaverse Inc., a subsidiary of JKN Global Group.
