Hayashi Hōkō (林 鳳岡, January 11, 1644 – July 22, 1732), also known as Hayashi Nobutatsu, was a Japanese Neo-Confucian scholar, teacher and administrator in the system of higher education maintained by the Tokugawa bakufu during the Edo period.

After 1691, Hōkō is known as the first official rector of the Shōhei-kō (afterwards known as the Yushima Seidō) which was built on land provided by the shōgun.

[1] This institution stood at the apex of the country-wide educational and training system which was created and maintained by the Tokugawa shogunate.

Gahō's hereditary title was Daigaku-no-kami, which, in the context of the Tokugawa shogunate hierarchy, effectively translates as "head of the state university".

[2] The scholars of the Hayashi school were taught to apply what they had learned from a Confucian curriculum.
