Fuki-ji (富貴寺) is Buddhist temple located in the city of Bungotakada, Ōita Prefecture Japan.

The temples related to Ninmon in the Kunisaki Peninsula area are collectively called Rokugōyama or Rokugō Manzan.

At Fuki-ji, there is a mask of an oni with an inscription dating from 1147; therefore the temple existed by this time, but details of what happened before then are unknown.

During the Tenshō era (1573-1592), many Buddhist temples were destroyed by the Kirishitan daimyō Ōtomo Sorin, but the main hall of Fuki-ji was spared.

The Ō-dō was built in the late Heian period, around the 12th century, and is a typical example of Amida-do architecture, as well as the oldest wooden structure in Kyushu.
