Back to Bedlam is the debut studio album by the English singer-songwriter James Blunt, released on 11 October 2004 by Custard and Atlantic Records. It is named after the famous psychiatric institution of Bethlem Royal Hospital, which is commonly known as Bedlam.

Initially lingering in the lower regions of the UK Albums Chart in its first few months of release, it became a major worldwide success after its third single, "You're Beautiful", became a worldwide hit in the summer of 2005. Back to Bedlam would go on to become the highest-selling album of 2005 in the UK, with over 2.4 million copies sold. By December 2009, the album had been certified 10× Platinum by the British Phonographic Industry for sales of over 3 million, making it the best-selling album of the 2000s in the UK. In 2011, it was overtaken by Amy Winehouse's Back to Black as the best-selling album of the 21st century in the UK. Back to Bedlam currently ranks as the 18th best-selling album in UK chart history and the biggest selling debut album by a British artist. As of 2017, it has sold 3.33 million copies in the UK and over 11 million copies worldwide.
