Menzan Zuihō (面山瑞方, 1683–1769) was a Japanese Sōtō Zen scholar and abbot of the Zenjo-ji and Kuin-ji temples active during the Tokugawa period.

Before Menzan the works of Dōgen were not widely studied or put into practice, he helped revitalize the Sōtō school by analyzing and building on Dogen's writings.

Due to Menzan's efforts, Dōgen studies now occupies a central position in Sōtō Zen thought.

[3] Menzan was the most prolific Sōtō zen scholar, having written over a hundred titles of detailed scholarship on monastic regulations, precepts, ordination, dharma transmission and philology.

One of his most famous works, the Buddha Samadhi (Jijuyu Zanmai) is addressed to laypeople and focuses on the teachings of Dōgen.
