The Shippōzan Motoyama-ji (Japanese: 七宝山 本山寺) is a Shingon Buddhist temple of the Kōyasan sect in Mitoyo, Kagawa, Japan. It was established by Emperor Heizei's instruction in 807.

The temple has undergone several reconstruction efforts since its founding, such as the rebuilding of its Main Hall (which is a National Treasure of Japan) in 1300.
