Siren is the fifth album by English rock band Roxy Music, released in 1975 by Island Records. It was released by Atco Records in the United States.

Roxy Music are an English rock band formed in 1970 by lead vocalist and principal songwriter Bryan Ferry and bassist Graham Simpson. By the time the band recorded their first album in 1972, Ferry and Simpson were joined by saxophonist and oboist Andy Mackay, guitarist Phil Manzanera, drummer Paul Thompson and synthesizer player Brian Eno. Other members over the years include keyboardist and violinist Eddie Jobson and bassist John Gustafson. The band split in 1976, reformed in 1978 and split again in 1983. In 2001, Ferry, Mackay, Manzanera and Thompson reunited for a concert tour and have toured together intermittently ever since, most recently in 2022 to celebrate the 50th anniversary of their first album. Ferry has also frequently enlisted band members as backing musicians during his solo career.
