“Rehab” is a song written and performed by English singer and songwriter Amy Winehouse, from her second and final studio album Back to Black (2006). Produced by Mark Ronson, the lyrics are autobiographical and address Winehouse’s refusal one time to enter a rehabilitation clinic. “Rehab” was released as the lead single from Back to Black on 23 October 2006, and it peaked at number 7 in the United Kingdom on its Singles Chart and number 9 in the United States on the Billboard Hot 100, becoming Winehouse’s only top 10 hit in the US.
“Rehab” has become a critical and commercial success internationally, and has been referred to as Winehouse’s “signature song”. It won three Grammy Awards at the 50th ceremony, including Record of the Year, Song of the Year, and Best Female Pop Vocal Performance. It also won an Ivor Novello Award for Best Contemporary Song. Winehouse’s public battle with drug and alcohol addiction, and subsequent death, have contributed to the song’s continuing popularity and appearance in the media.
The documentary film Amy (2015) and its soundtrack feature a 2006 performance of the song by Jools Holland. The song has been covered by a list of artists, such as Hot Chip, Lea Salonga, Seether, and the Jamaican Mento band The Jolly Boys.
