Emperor Shijō (四条天皇, Shijō-tennō) (17 March 1231 – 10 February 1242) was the 87th emperor of Japan, according to the traditional order of succession. This reign spanned the years 1232 through 1242.

Before his ascension to the Chrysanthemum Throne, his personal name (his imina) was Mitsuhito-shinnō (秀仁親王), also known as Tosihito-shinnō.

He was the first son of Emperor Go-Horikawa.

Consort: Kujō Genshi (九条 彦子; 1227–1262) later Nishinomon’in (宣仁門院), Kujō Norizane’s daughter

He had no children, due to his youth at the time of his death.

He reigned from 26 October 1232, to 10 February 1242.

Emperor Shijō died from an accident in 1242. His Imperial tomb (misasagi) is at Sennyū-ji in the Nochi no Tsukinowa no Higashiyama no misasagi (後月輪東山陵).

As the Emperor was very young, and the Retired Emperor Go-Horikawa died just two years later, most of the actual leadership was held by his maternal relatives Kujō Michiie and Saionji Kintsune.
