"Tonight, Tonight, Tonight" is the second track on the 1986 album Invisible Touch by Genesis. It peaked at No. 3 in the U.S. and No. 18 in the UK as the fourth single from the album. The working title was "Monkey, Zulu".

The single included an edited version (at 4:32) and the first part of "Domino" ("In the Glow of the Night") as the B-side. A new edit of the single version was released on the 1999 compilation Turn It On Again: The Hits (as well as its "sequel" The Tour Edition) and later on The Platinum Collection. This revised edit features a different cross fade and different edit points as compared to the original 1987 edit version. Some singles that included the full version of the song included the second part of "Domino" ("The Last Domino") as the B-side. Other releases contained the song "Paperlate" and a 12" remix of "Tonight, Tonight, Tonight". The full live version from the Live at Wembley Stadium video was included as a B-side on the "Tell Me Why" CD single.

The song was performed during concerts in support of Invisible Touch. A shorter version (which segued into "Invisible Touch") was played on the We Can't Dance and Turn It On Again tours, albeit transposed down a key to account for the deepening of Phil Collins' voice.

The music video for the song has an atmosphere reminiscent of the film Blade Runner, which was purportedly a source of inspiration for the video. It was shot in the Bradbury Building in Los Angeles, where as was Blade Runner and many other music videos and sci-fi productions.
