"AM" is the fifth studio album by the English rock band Arctic Monkeys, released on 9 September 2013 through Domino Recording Company. It was produced by longtime collaborator James Ford and co-produced by Ross Orton at Sage & Sound Recording in Los Angeles and Rancho De La Luna in Joshua Tree, California. The album was promoted with the singles "R U Mine?", "Do I Wanna Know?", "Why'd You Only Call Me When You're High?", "One for the Road", "Arabella", and "Snap Out of It". It features guest appearances by Josh Homme, Bill Ryder-Jones, and Pete Thomas.
 
Drawing inspiration from a wide range of genres, including psychedelic rock, blues rock, hard rock, heavy metal, desert rock, R&B, funk, and soul, AM marks Arctic Monkeys' first venture into a hip hop-influenced sound. According to frontman Alex Turner, the band took a different approach to recording this album compared to their previous one, Suck It and See (2011), with more emphasis on creating a "studio album." They incorporated new instruments such as the piano, organ, Hohner Guitaret, and vintage drum machine. Thematically, the album explores frustration surrounding tainted romance, sex, and loneliness.
 
Commercially, AM became one of Arctic Monkeys' most successful albums, topping charts in several countries and reaching top ten positions in many others. It topped the UK Albums Chart, selling over 157,000 copies in its first week, and went on to become one of the UK's best-selling vinyl albums of the decade, selling 73,000 units. It also became the band's most successful album in the United States, with the single "Do I Wanna Know?" becoming their first song to enter the Billboard Hot 100. The album topped four Billboard charts and was certified seven-times platinum in the US by the Recording Industry Association of America (RIAA) in 2023. AM received critical acclaim for its darker and groovier sound compared to the band's previous records. It appeared in many year-end lists as one of the best albums of 2013, with the BBC naming it the best of the year. At the 2014 Brit Awards, Arctic Monkeys won British Album of the Year for AM. It was also nominated for the 2013 Mercury Prize and received a Best Rock Performance nomination for "Do I Wanna Know?" at the 57th Grammy Awards in 2015. NME hailed it as the best album of the decade and, just a month after its release, ranked it 449 on their list of the 500 Greatest Albums of All Time. Rolling Stone ranked it 346 in the 2020 edition of its "500 Greatest Albums of All Time" list.
