18 is the sixth studio album by American electronica musician, songwriter, and producer Moby. It was released on May 13, 2002, by Mute Records in the UK and on May 14, 2002, by V2 Records in the US. After the unexpected commercial and critical success of his previous album, Play (1999), Moby started to write songs for a follow-up during its supporting tour. He started work on the album at its conclusion in December 2000, using fewer samples than before. Guest vocalists include Azure Ray, MC Lyte, Angie Stone, and Sinéad O'Connor.

Richard Melville Hall, known professionally as Moby, is an American musician, songwriter, singer, producer, and animal rights activist. He has sold 20 million records worldwide. AllMusic considers him to be "among the most important dance music figures of the early 1990s, helping bring dance music to a mainstream audience both in the United States and the United Kingdom".
