Mount Hōman (宝満山, Hōman-san), is a mountain on the border between the cities of Chikushino and Dazaifu in Fukuoka Prefecture in Kyūshū, Japan.

The mountain has a history closely related to Dazaifu since ancient times and is mention in the Nihon Shoki as the guardian of the land of Tsukushi.

Because of the syncretization of Shinto and Buddhism, the deity enshrined on this mountain was named "Hōman Daibodhisattva", and as the mountain was located to the "unlucky" northeast direction from the government offices at Dazaifu, it functioned similar to Mount Hiei at Heian-kyō.

In 803, Saichō carved a statue of Yakushi Nyorai of the Kamadozan-ji in order to pray for safety during his crossing to Tang China.

Archaeological excavations and topographical surveys have been conducted since in 2005, with an aim of preserving any ruins which have been endangered by heavy rains in recent years.
