Racjin (株式会社ラクジン, Kabushiki-gaisha Rakujin), formerly known as Racdym (株式会社ラクディム, Kabushiki-gaisha Rakudimu), is a Japanese video game development company located in Yodogawa-ku, Osaka, which was established in April 17, 1995. Its name was changed in 2000 to make it more easily pronounceable for the Japanese.

Their first game was Far East of Eden: Kabuki Klash, which was published in 1995 for the Neogeo. They were not well-known until 1997, when Atlus published Snowboard Kids. They also have worked on games based on existing franchises, such as Fullmetal Alchemist, Bleach, and Bomberman. In 2007, they worked on Mistwalker's project, ASH: Archaic Sealed Heat.
