Hōrai-ji (鳳来寺), Buddhist temple of the Shingon sect located in the city of Shinshiro, Aichi Prefecture, Japan.

Per the temples own history, it was founded in 702 AD by a holy ascetic, Ryūshū Sennin, who carved statues of Yakushi Nyōrai, Nikkō Bosatsu, Gakkō Bosatsu, the Jūni Shinshō, Shi-Tennō and other deities out of the living trucks of trees on Mount Hōrai.

The temple was rebuilt in the Kamakura period by Minamoto no Yoritomo (who is also credited with building the 1425 stone steps), out of gratitude for sheltering him during the Heiji rebellion.

The temple suffered from repeated fires during the Kamakura and Muromachi periods, so most written records have been destroyed; however, the archaeological record in the form of many pottery shards and sutra mounds indicates that the temple existed as a center of both Buddhism and folk religion into the Sengoku period.

Hōrai-ji recovered considerably during the Edo period, and it was especially favored by Odai no Kata (Tokugawa Ieyasu's mother).
