Omega Tribe (Japanese: オメガトライブ, Hepburn: Omega Toraibu) was a Japanese music project led by producer Koichi Fujita from 1983 to 1995. With the help of composers Tetsuji Hayashi, Tsunehiro Izumi, and Hiroshi Shinkawa, the project had three different bands with three different lead vocalists: Kiyotaka Sugiyama (1983–1985), Carlos Toshiki (1986–1991), and Masahito Arai (1993–1994). Under Fujita's directions, recordings were performed by studio musicians and production handled by the project's production team. The project has been described as helping form the city pop sound, especially with the project's usage of summer and sea themes.

S. Kiyotaka & Omega Tribe (杉山清貴&オメガトライブ) was the first band in the project that was active from 1983 to 1985. It consisted of lead vocalist Kiyotaka Sugiyama, rhythm guitarist Shinji Takashima, lead guitarist Kenji Yoshida, keyboardist Toshitsugu Nishihara, bassist Takao Oshima, and drummer Keiichi Hiroishi. The band was initially formed as Cutie Panchos (きゅうてぃぱんちょす) in 1978, the band was scouted by Fujita after their performance at the 20th Yamaha Popular Song Contest in 1980.

Fujita and composer Tetsuji Hayashi produced their discography, which consisted of five albums: Aqua City (1983), River's Island (1984), Never Ending Summer (1984), Another Summer (1985), and First Finale (1985). The band consistently ranked on the top ten on the albums chart, with their final two albums Another Summer and First Finale topping the charts in 1985. Growing frustration from the members towards the production team, which hired studio musicians to complete the band's work on studio recordings, eventually made the band decide to break up in 1985 at the peak of their popularity.
