All Nighters

 (オールナイターズ) was a J-Pop idol group that originally lasted from 1983 to 1985. The group consisted of a rotational, all-female group of co-hosts/MCs of the Fuji TV program, All Night Fuji. Members were required to be enrolled in college, university, or another similar extended education program while they were active in the group.

After an official restructure of its parent television show, the group relaunched later that year with reduced musical activities. Around 1988 is when the group stopped producing music completely, but still performed TV-hosting duties until All Night Fuji 's cancellation in 1991. Their successor group is C-X.

This group is notable for being the first large scale rotational idol unit in J-pop, as well as the first to include sub-units. Onyanko Club was also created using a slightly modified format of the All Nighters. Several early audition candidates for Onyanko Club were sourced from All Nighters.
