Riki-Oh (Japanese: 力王, Hepburn: Riki-Ō^?) is a manga which later adapted to two OVAs and a live-action film named Riki-Oh: The Story of Ricky.

Created by Masahiko Takajo and Tetsuya Saruwatari, the story is about a young man who has learned the art of Qigong from one of Chiang Kai-shek's bodyguards and has become so strong that he can literally punch holes through people and solid objects. It was serialized in Business Jump from 1987 to 1990 and later published in 12 volumes.

Outside Japan, it was translated and published only in Hong Kong by Comicsworld in nine volumes. The only difference between the two editions, besides the different number of pages in each volume, is the absence of the short story "N.Y. Dust", which is unrelated to Riki-Oh, in the Hong Kong edition.

The story is set in a post-apocalyptic future where global warming has devastated most of the earth and the world is suffering from an economic depression which led to increased crime.

The story centers around Saiga Riki-Oh, blessed with inhuman strength, who, after taking revenge against a yakuza who was responsible for the death of a child who befriended him (in the movie, it was his girlfriend who died), ends up in a maximum security prison owned by a private organization. The story follows Riki and his search for his little brother Saiga Nachi, who bears a Manji symbol on his right hand and also possesses superhuman strength.
