Kokerbin Rock, Rock formation in Bruce Rock Shire, Western Australia.

Kokerbin Rock is a granite monolith in Kokerbin Nature Reserve, in Western Australia's Wheatbelt. Marked bush walks lead to its summit, caves and rock formations, among them a wave rock formation, Dog Rock and Devil's Marbles. A historic stone well and an old school site stand on its western side.

Kokerbin Nature Reserve, which contains the rock, was established in 1991 and covers 91 hectares. On the western side of the rock stand a historic stone well and an old school site, remains of early European settlement in the area.

Kokerbin Rock and its reserve hold particular cultural meaning for the Noongar Aboriginal peoples of the Wheatbelt. The sources record this link without detailing naming traditions or meanings, so visitors should treat the rock, caves and summit as a Noongar cultural landscape rather than only a geological site.

The eastern section has restroom facilities and a designated picnic area with established pathways leading to caves and the summit. The site is easy to explore on foot and visitors should plan time to see the different areas and trails.

Kokerbin Rock is often called Australia's third-largest monolith, behind Uluru and Mount Wudinna, though some sources give that rank to Bald Rock. The claim rests on size estimates rather than a formal survey, so visitors will find it repeated in local accounts without an official measurement.
