Tonight is the sixteenth studio album by the English singer-songwriter David Bowie, released on 24 September 1984 through EMI America Records. The follow-up to his most commercially successful album Let's Dance, it was written and recorded in mid-1984 at Le Studio in Morin-Heights, Canada, following the conclusion of the Serious Moonlight Tour. Bowie, Derek Bramble and Hugh Padgham co-produced the album. Many of the same personnel from Let's Dance and the accompanying tour returned for Tonight, with a few additions. Much of Bowie's creative process was the same as he used on Let's Dance, similarly playing no instruments and offering little creative input to the musicians.

The music on Tonight has been characterised as pop, blue-eyed soul, dance and rock. Much of the album's sound is the same as its predecessor's, due to Bowie's effort to retain the new audience that he had recently attracted, although some tracks contain R&B and reggae influences. Devoid of new ideas from touring, Bowie wrote only two new songs himself. Three songs, including the title track, were covers of Iggy Pop songs, who was present during most of the sessions and co-wrote two tracks. The title track is a duet with singer Tina Turner. The artwork, featuring Bowie blue-painted against an oil painting backdrop, was designed by Mick Haggerty.

Supported by the singles "Blue Jean", "Tonight" and "Loving the Alien", Tonight was a commercial success, reaching number one on the UK Albums Chart. Critical reception was poor, with most finding a lack of creativity. Following the critical dismissal of his next studio album Never Let Me Down (1987), Bowie expressed dissatisfaction with this period, calling Tonight not one of his stronger efforts, a sentiment echoed by later commentators. He did not tour to support the album and only performed "Loving the Alien" and "Blue Jean" on subsequent tours. The album was remastered in 2018 as part of the box set Loving the Alien (1983–1988).
