Kujo Yoritsune (九条 頼経 Kujō Yoritsune) (1218-1256) was the fourth shogun (r. 1226-1244) of the Kamakura shogunate of Japan. His father was kampaku Kujo Michiie and his grandmother was a niece of Minamoto no Yoritomo. Kujo Yoritsune is also known as Fujiwara no Yoritsune.

At the age of seven, in 1226, Yoritsune became Seii Taishogun in a political deal between his father and the shogunate regent Hojo Yoshitoki and Hojo Masako who set him up as a puppet shogun.

In 1244, he relinquished the position of shogun to his son Kujo Yoritsugu. In the next year, he became a Buddhist priest.
