Red Garden (stylized as RED GARDEN) is a Japanese anime television series produced by Gonzo which premiered in Japan on TV Asahi on October 3, 2006. The plot revolves around four girls who become involved in a series of supernatural murders happening throughout the vicinity of a fictional depiction of New York City. An OVA sequel called Dead Girls was released in Japan, on August 8, 2007.

A manga of the same title began serialization in the seinen manga magazine Comic Birz on August 30, 2006. The first tankōbon was released on February 24, 2007.

Red Garden employs a technique often used by animated productions outside Japan, but rarely used in Japanese animation. The characters' dialogue is animated after the work of the voice cast, synchronizing the animation with the voice actors' voices. The synchronization is particularly evident in scenes where characters are singing (occurring in some of the earlier episodes).

Red Garden was licensed for release in English by ADV Films for $660,000 and the first DVD was released on September 18, 2007. ADV Films' Anime Network began airing the anime on September 13, 2007 on their Subscription On Demand platform. On March 6, 2008 the anime began airing on their Free On Demand platform. Funimation acquired the series Red Garden in 2008.
