Saichō (最澄, 767–822) was a Japanese Buddhist monk credited with founding the Tendai school in Japan, based around the Chinese Tiantai tradition he was exposed to during his trip to China beginning in 804. He founded the temple and headquarters of Tendai at Enryakuji on Mt. Hiei near Kyoto. After his death, he was awarded the posthumous title of Dengyō Daishi (伝教大師).
