Astronaut is an album by British band Duran Duran, first released on October 11, 2004 (see 2004 in music).

This was Duran Duran's first studio album since Pop Trash (2000), and the first full album since Seven and the Ragged Tiger (1983) to be recorded by the original five members of the band. (The stand-alone single "A View to a Kill" was their last studio recording together.)

Duran Duran are an electronic pop-rock band, often classified into the aggregate "80s rock" genre and notable for a long series of catchy, synthesizer-driven hit singles and vivid music videos. They were part of the New Wave music movement in the early 1980s (the most commercially successful of the New Romantic bands), as well as a leading band in the MTV-driven Second British Invasion of the United States. They are still often identified as an Eighties band despite continuous recording over their twenty-plus year history
