Ōmidō temple ruins (大御堂廃寺跡, Ōmidō Haiji ato) is an archeological site with the ruins of a Nara period Buddhist temple located in the Daikyōji- neighborhood of the city of Kurayoshi, Tottori prefecture, in the San'in region of Japan.

Locals had long suspected ancient ruins in the area, and the foundation stones of a Japanese pagoda were found when the site was cleared for a factory in 1952.

North of the Lecture Hall were two buildings consisting of three rooms each on the east and west sides, believed that have been priest's quarters.

Excavated artifacts included a large quantity of roof tiles, earthenware, and wooden and metal items.

[2] Some earthenware is labelled "Kume-dera" (久米寺) in black ink, which may have been the name of the temple as it is located in Kume district of Hōki Province, approximately five kilometers east of the location of the Hōki Provincial Capital; however, the temple does not appear in historical documentation, and its history is unknown.
