Yazoo (also known as Yaz in the United States) is a British synthpop duo from Basildon, Essex. It had a number of Top 10 hits in the UK charts in the early 1980s. Formed in late 1981 by former Depeche Mode songwriter Vince Clarke (synthesizer) and Alison Moyet (vocals), Yazoo was signed to Mute Records in the United Kingdom and (as "Yaz") to Sire Records in the United States.

Yazoo's debut single "Only You" backed with "Situation", was released on 15 March 1982 and rose to number two in the UK charts. Yazoo released two successful studio albums, Upstairs at Eric's in 1982 and You and Me Both in 1983. Shortly after, Moyet and Clarke decided to break up. Moyet pursued a solo career while Clarke went on to form Erasure, another synth pop duo. Yazoo reunited in 2008 with a tour in Europe and the United States and the release of a four-disc box set.

Though the band's initial run was short-lived, Yazoo continues to influence and inspire many of today's bands, including LCD Soundsystem, Shiny Toy Guns, Blaqk Audio, Hercules and Love Affair, La Roux and Gil Mantera's Party Dream.
