Murchison River Gorge is a riverine gorge in Mid West Western Australia. Carved by the meandering lower reaches of the Murchison River, it is more than 80 kilometres long, and up to 129 metres deep. It begins about 13½ kilometres north-northwest of Ajana, and extends to the mouth of the river at Kalbarri. Widely considered a site of outstanding natural beauty, it is a major tourist attraction.
