Mokujiki Shōnin (木喰明満, 1718–1810) was an itinerant Japanese Buddhist monk who carved more than a thousand devotional sculptures while walking on pilgrimage across Japan — from Hokkaidō to Kyūshū — subsisting on a strict ascetic diet of tree seeds and nuts. He carved without apprentices, without a workshop, and without formal training in the established sculptural traditions.

In 1924, the folkcraft theorist Yanagi Sōetsu encountered a collection of Mokujiki works at Kyōan-ji in Niigata, and published the first systematic study the following year. Yanagi identified in Mokujiki's carvings the concept of mushin (無心) — unselfconscious grace — and credited them as the catalyst for his formulation of the Mingei movement's foundational concept of innate Japanese beauty (固有な日本の美).
