Kōyasan chōishi-michi (高野山町石道) is a pilgrimage route on the Kii Peninsula in the Kansai region of Japan.

It begins at the Jison-in temple in the town of Kudoyama on the south bank of the Kinokawa River and extends twenty-four kilometres to Mount Kōya, or Kongōbu-ji Temple, the ecclesiastical headquarters of the Kōyasan sect of Shingon Buddhism in the town of Kōya.

The Kōyasan chōishi-michi is claimed to be the route created by Kūkai when he first established Kongōbu-ji in 819 AD.

Of these, 180 were on the 22 kilometer path from Jison-in to the Danjō Garan,and a further 36 were erected on the further four kilometres to Kūkai's mausoleum in Okunoin Cemetery.

During the Kamakura period, a priest of Mount Kōya obtained donations from the Imperial Family and a number of leading warlords, and began replacing these wooden markers with granite five-tiered stupas over a 20 year period, with the project completed in 1285.
