Fukugon-ji (福厳寺) is an Ōbaku Zen temple in Yanagawa, Fukuoka, Japan.

Its honorary sangō prefix is Baigakuzan (梅岳山).

In 1587, however, Tachibana Muneshige who was granted the three districts of Chikugo Province, Yamato, Shimotsuma and Mizuma and built a castle in Yanagawa, started to move to the present location.

Tadashige invited Tetsumon Dōchi, the elder son of Mu'an and changed the name to Fukugon-ji.

There is a cemetery in the back of the main hall, and the graves of some famous novelists such as Ken Hase, Kazuo Dan etc.
