Kujō Ninshi

, also known as and Gishūmon-in (宜秋門院), was an empress consort of Japan. She was the consort of Emperor Go-Toba.

In 1190, she was appointed as Go-Toba's empress. This was likely part of political manoeuvring by her father, Kujō Kanezane, who was appointed regent the next year.

In 1195, Ninshi gave birth to a daughter. Unusually and suddenly, a year later Ninshi left the palace. There has been speculation as to the reason behind this departure: a leading theory suggests that it was arranged by rival families as part of an attempt to overthrow her father, Kanezane.

Upon the death of her mother in 1201, she undertook the Buddhist precepts under the monk Hōnen.
