Okyō (於京) or Okyō no kata was a Japanese female warrior (onna-musha) from the Sengoku period. She served Aso Koremitsu alongside her husband, Kiyama Masachika. When Higo province was divided between Konishi Yukinaga and Katō Kiyomasa in 1587, on the completion of the Kyushu Campaign, Kiyomasa invaded the lands of the Aso clan and she volunteered for the defense.
