DigiCube Co., Ltd. (株式会社デジキューブ; Kabushiki-gaisha Dejikyūbu) was a Japanese company established as a subsidiary of software developer Square on February 6, 1996 and headquartered in Tokyo, Japan.

The primary purpose of DigiCube was to market and distribute Square products, most notably video games and related merchandise, including toys, books, and music soundtracks.

DigiCube served as a wholesaler to distributors, and was noteworthy for pioneering the sale of video games in Japanese convenience stores and vending machine kiosks.

Following the announcement that the much-anticipated Final Fantasy XII would be delayed until sometime in 2004 (eventually released in 2006), DigiCube filed for bankruptcy liquidation at the Tokyo District Court on November 26, 2003.

Ultimania (アルティマニア, Arutimania, a portmanteau of ultimate and mania)[9] is a series of video game books originally published in Japan by DigiCube and written by Studio BentStuff.
