Night Wizard! (Japanese: ナイトウィザード, Hepburn: Naito Wizādo) is a Japanese contemporary fantasy role-playing game designed by Takeshi Kikuchi and FarEast Amusement Research (F.E.A.R.) released in 2002. In the modern-day earth campaign setting, player characters called Wizards (ウィザード) fight against the world enemy named Emulators (エミュレーター) and their lords Maō (魔王) and explore the dungeons built by Emulators.

The game's campaign session (played by F.E.A.R.'s staff and voice actors) logs named replays were published in non-RPG magazines such as E-LOGIN and Magi-Cu, therefore, Night Wizard! fans are not limited to only RPG gamers.

An anime television series adaptation animated by Hal Film Maker began airing in Japan in October 2007 and ended its run on December 25, 2007. Night Wizard! actively diversifies into other media contents including replays, drama CD, manga, computer games and light novels and so on.
