Mobile Suit Gundam 0080: War in the Pocket (Japanese: 機動戦士ガンダム0080 ポケットの中の戦争, Hepburn: Kidō Senshi Gandamu 0080 Poketto no Naka no Sensō) is a six episode 1989 Japanese science fiction original video animation series. It is the first OVA series in the Gundam franchise. It was directed by Fumihiko Takayama, written by Hiroyuki Yamaga with character designs by Haruhiko Mikimoto.

As suggested by its subtitle, "War in the Pocket", it is a small, personal story; a side story focusing on the experiences of an eleven-year-old boy during the One Year War and his learning of the real meaning of war. A significant departure for the Gundam franchise at the time, Gundam 0080 has received wide acclaim from critics.
