Kőris-hegy, Volcanic mountain in Hungary.

Kőris-hegy is a volcanic mountain in Veszprém County that reaches about 700 meters in height. Its slopes display varied rock formations and natural terrain shaped by ancient volcanic activity.

Kőris-hegy is the highest point of the Bakony at 709 m, in Veszprém County within the Magas-bakonyi Landscape Protection Area, 5 km northeast of Bakonybél. Its Odvas-kői-barlang cave has been under archaeological protection since 1951 and strictly protected since 1982; the name Oduaskw appears in a 1037 charter of King Stephen I, the earliest written Hungarian place name referring to a cave. In 1976 a long-range radar station for civil air traffic control was built on the summit, operated by HungaroControl.

The name comes from the ash (kőris) forests covering its slopes.
