Jōkō-ji (定光寺) is a Buddhist temple belonging to the Myōshin-ji branch of the Rinzai school of Japanese Zen, Buddhism located in the city of Seto, Aichi Prefecture, Japan.

The temple is noted for the mausoleum of Tokugawa Yoshinao, the son of Tokugawa Ieyasu and founding daimyō of Owari Domain; however it was not the bodaiji of the clan.

The temple was founded in 1336 under the sponsorship of Mizuno Munekuni, one of the ancestors of the Mizuno clan, and initially belonged to the Kencho-ji branch of the Rinzai school.

The Hondō of the temple[1] and the six structures comprising the tomb and memorial chapel for Tokugawa Yoshinao are designated Important Cultural Properties.
