The Carpentarian rock rat (Zyzomys palatalis) is a species of rodent in the family Muridae.

The holotype was a pregnant female, collected at Wollogorang Station, in a deep ravine called Echo Gorge.

The average weight of individuals is about 120 g. It has a very limited range, being currently known from only five localities within the Wollogorang Station pastoral lease of the Northern Territory, close to the border with Queensland, near the Gulf of Carpentaria.

Crucial habitat characteristics are rugged sandstone gorges with a cover of dry monsoon vine-thicket or tropical woodland, and with access to permanent water.

It is subject to conservation management, including a captive breeding program at the Territory Wildlife Park.
