Snow (スノー, Sunō) is a Japanese adult visual novel developed by Studio Mebius for Windows PCs on January 31, 2003. It was later ported without the erotic content to the Dreamcast, PlayStation 2, and PlayStation Portable consoles. The story of Snow revolves around the life of Kanata Izumo, who is revisiting a village to help his relative manage a hot spring inn. The gameplay in Snow follows a branching plot line which offers pre-determined scenarios with courses of interaction, and focuses on the appeal of the female main characters by the player character.

The game was successful in both sales and popularity, it was ranked as the best-selling PC game sold in Japan at the time of its release, and charted in the national top 50 several more times afterward. Snow was voted as the twenty-sixth best bishōjo game by the readers of Dengeki G's Magazine in 2007. A manga titled Snow: Pure White based on the visual novel was serialized in Comptiq between the September and December 2003 issues. Five light novels and several comic anthologies were also released, as were audio dramas. Studio Mebius went on to release a visual novel called Tomodachi Ijō Koibito Miman on September 24, 2004, which shares the same setting and characters from Snow but takes place years later and focuses on Meiko Tachibana.
