Kujō Tadanori (九条 忠教) was Chancellor of Japan in the apex of his career.
Kujō Tadanori was born into the Kujō clan, a branch of the Fujiwara clan, as the son of Kujō Tadaie. He thus may be called Fujiwara Tadanori in old texts. He had sons: Kujō Moronori and Kujō Fusazane.
The Ōoka clan claimed descent from him, although this is highly unlikely.
His tenure as Chancellor lasted from 1291 to 1293; in that title, he was preceded by Konoe Iemoto and succeeded by Konoe Iemoto.[DNHS-377]
