Sengaku (仙覚, 1203 – c. 1273) was a Japanese Buddhist monk of the Tendai school. He was a scholar, editor and a literary critic.^[1]

His major work, Man'yōshū chūshaku, was completed in 1269. This was a treatise on the collected poems in the Man'yōshū anthology.^[1] His work was instrumental in a process of rediscovering the original meaning of this seminal work of Japanese poetry.

Sengaku's published writings encompass 9 works in 12 publications in 1 language and 53 library holdings.^[2]
