Kazanin Iesada (花山院 家定; 27 July 1283 - 2 June 1342) was Minister of the Right of Japan in the apex of his career.
Kazanin Iesada was born into the Kazanin clan, a branch of the Fujiwara clan, as the son of Kazanin Ienori, who was the son of Kazanin Michimasa. He thus may be called Fujiwara Iesada in old texts.
His tenure as Minister of the Right lasted from 1318 to 1319; in that title, he was preceded by Saionji Kinaki and succeeded by Kujō Fusazane.
