Saitō Myōchin (斎藤 妙椿, 1411 – April 1, 1480) was a Japanese daimyo and a monk during the Sengoku period.
[1] Myōchin was the son of Saitō Sōen (斎藤宗円), who served as the guardian of Mino Province, and the younger brother of Saitō Toshinaga.
He began his training as a monk from a young age at Zene-ji (善恵寺).
In 1450, Saitō Myōchin served as the guardian of upper Mino Province on behalf of the Toki clan.
When Yoshinaga died in 1460, Myōchin moved from Jōzai-ji and into nearby Kanō Castle.
