Green Green (グリーングリーン, Gurīn Gurīn?) is a Japanese, 13-episode anime adaptation of the H-game of the same name. While there are no sexually explicit scenes in the first 12 episodes, the series has a strong focus on nudity. Episode 13 is missing from the US release due to multiple scenes involving sexual acts.

Media Blasters has licensed Green Green for distribution in North America, and the first volume was released on May 16, 2006.
