25

25 is the third studio album by the English singer-songwriter Adele, released on 20 November 2015 by XL Recordings and Columbia Records. The album is titled as a reflection of her life and frame of mind at 25 years old and is termed a "make-up record".

In the United Kingdom, 25 debuted at number one on the UK Albums Chart and sold 800,307 copies in its first chart week, overtaking Oasis' Be Here Now (1997) to become the fastest-selling album of all time in the UK. Of that total, 252,423 copies were digital downloads, breaking the record for most digital copies sold in a week, and 548,000 were physical copies. In its first week, 25 sold more copies in the UK than the combined sales of the last 19 number-one albums in UK on their debut week.

In December 2016, it became only the third album to be the UK's biggest-seller two years in a row, after Simon & Garfunkel's Bridge over Troubled Water (1970 and 1971) and Simply Red's Stars (1991 and 1992). 25 has sold over 3.50 million copies as of October 2018, making it the tenth best-selling album in UK history. As of October 2019, the album is the third best-selling album of the 21st century in the UK. In the UK's Top 10 Albums by Female Recording Artists for the period 2000–2021, 25 ranked No. 3, with 21 at No. 1.
