30 is the fourth studio album by English singer-songwriter Adele, released on 19 November 2021 by Melted Stone and Columbia Records. The album centers on Adele's divorce, motherhood, and the scrutiny of fame, with themes of heartache, acceptance, and hope. Adele wrote 30 between 2018 and 2021 with producers including Greg Kurstin, Tobias Jesso Jr., Max Martin and Shellback, all of whom worked on her previous record, 25 (2015); new collaborators include Ludwig Göransson, and Inflo of the English band Sault. American jazz pianist Erroll Garner is posthumously credited as a featured artist on "All Night Parking", marking the first guest performance on a standard album by Adele.

30 received critical acclaim for its cinematic instrumentation, vocal performances and honest themes. The album appeared on many year-end lists, and was considered to be Adele's most versatile album, incorporating elements of dance-pop, rhythm and blues, soul, and jazz. As Adele's return to the music industry following the release of 25 six years earlier, 30 was one of the most anticipated releases of 2021, and was a major commercial success. It topped the charts in 22 territories, including Australia, Germany, the Netherlands, the United Kingdom and the United States, where it became Adele's third number-one album on the Billboard 200. It was the highest-selling album of 2021 in the United States, becoming Adele's third consecutive album to achieve this feat.

The lead single, "Easy on Me", was released on 15 October 2021 to international success, topping the charts in 26 countries. The extensive promotional campaign included a CBS concert special, Adele One Night Only, featuring an interview by American talk show host Oprah Winfrey, on 14 November 2021, followed by an ITV concert special, An Audience with Adele on 21 November 2021. Two British Summer Time Hyde Park are scheduled for July 2022.
