Narcissu (Japanese: ナルキッソス, Hepburn: Narukissosu) is a free visual novel video game developed by the dōjin group Stage-nana, telling the story of a terminally ill young man and woman.

Both the original Japanese visual novel and its English version were released as free downloads over the Internet.

The anonymous protagonist is diagnosed with lung cancer shortly after his twentieth birthday, and is admitted to hospice care at a hospital in Mito, Ibaraki.

There he meets Setsumi, a woman who is two years older than he is, who is also terminally ill. Finding that they both refuse to die in the hospital or at home with their families, they run away together in a silver Honda Integra belonging to the protagonist's father.

They travel west across Japan's many highways and prefectures, initially not knowing where to go, but later collectively decide on taking the narcissus fields of southern Awaji Island as a somewhat arbitrary destination.

12 of the game's music tracks are accessible on-demand via the in-game jukebox, which is called the "Sound Mode".
