Bangerz is the fourth studio album by American singer Miley Cyrus. It was released on October 4, 2013, by RCA Records. Opting to re-establish her music career instead of focusing on her film career as originally planned, Cyrus began planning the project in 2012. Work continued into 2013, at which time she left her previous label Hollywood Records and subsequently joined RCA Records. Described by Cyrus as "dirty south hip-hop", Bangerz represents a musical departure from her earlier work, which she has grown to feel "disconnected" from. As executive producers, Cyrus and Mike Will Made It collaborated with hip hop producers including Cirkut, Pharrell Williams, and will.i.am to achieve Cyrus' desired new sound. Their efforts resulted in a primarily pop record, with lyrical themes that revolve largely around romance. It features guest vocals from several new partners, including pop singer Britney Spears and rappers French Montana, Future, Ludacris, and Nelly.

Bangerz received mixed reviews from contemporary music critics, who appreciated its overall production and originality, but were ambivalent towards Cyrus' public persona. The record debuted at number one on the U.S. Billboard 200 with first-week sales of 270,000 copies. In doing so, it became Cyrus' fifth non-consecutive number-one album, including earlier soundtracks in which she performed as her former titular character Hannah Montana. It was the third-highest opening week for a female artist in 2013, and was later certified platinum by the Recording Industry Association of America (RIAA) after moving one million units. The album received a Grammy Award nomination for Best Pop Vocal Album, giving Cyrus her first Grammy nomination.

"We Can't Stop" was released as the lead single from Bangerz on June 3, 2013, and peaked at number two on the US Billboard Hot 100. The second single "Wrecking Ball" was released on August 25, 2013, and became Cyrus' first single to peak in the top position in the United States. Its accompanying music video currently holds the record for the fastest video to reach 100 million views on Vevo, it also earned Cyrus the award for "Video of The Year" at the 2014 MTV Video Music Awards. "Adore You" was serviced as the third single from the record on December 17, 2013; it has peaked at number 21 on the Billboard Hot 100. A remix of the track produced by Cedric Gervais was released on March 3, 2014. Promotional efforts for Bangerz continued to associate Cyrus with an increasingly provocative image, an effort first begun with her third record, Can't Be Tamed (2010). She garnered widespread media attention through a controversial performance at the 2013 MTV Video Music Awards, and was later the host and musical guest during an episode of Saturday Night Live. Furthermore, Cyrus promoted the album with her international Bangerz Tour. As of 2014, the album had sold 4.5 million copies worldwide.
