Ornon (Greek: Ὄρνον) is a mountain range in Lasithi in eastern Crete, Greece.
Part of the Sitia Mountains, it is northeast of Thrypti and south of the Western Siteia Foothills, which border on the north coast to the west of Sitia.
The Ornon mountains are entirely in the municipality of Ierapetra in Lasithi regional unit.
The canyons, or gorges, are cut deeply into the edges of the massif by runoff from above, a process facilitated by the softness and solubility of limestone.
