Ochi Ienori served as a bushō during the Sengoku period.  He held the titles of Inspector of the Board of Censors and Assistant Vice Minister of Justice.

Ienori was born as the son of Ochi Iehide, a kokujin, or provincial landowner, in Yamato Province.  Ienori’s childhood name was Kosaburō.

Together with his father, Ienori expanded the influence of the Ochi clan in Yamato.  In 1497, after Hatakeyama Hisanobu attacked Hatakeyama Yoshitoyo, Tsutsui Junken and Tōichi Tōharu invaded Yamato, defeating Ienori and Iehide.  Along with Furuichi Chōin, the Ochi clan experienced a setback, but revived in Yamato the following year.

In 1500, following the death of Iehide, Ienori succeeded his father as head of the Ochi clan, and, in 1505, reconciled with Tsutsui Junken and his followers, arranging for his daughter to wed Junken.  In 1506, however, Akazawa Tomotsune invaded Yamato.  To resist, the kokujin families in Yamato formed the Yamato kokujin ikki – an alliance formed for the purposes of protecting the rights of landowners.  Meanwhile, Ienori appeared to have died in 1507.
