Thornton Peak is a prominent mountain that rises above the Daintree Rainforest to a height of 1374 m.[1] The mountain is located about 126km northwest of Cairns within the catchment of the Daintree River.

The indigenous Eastern Kuku Yalanji people's name for Thornton Peak is Wundu, and it has spiritual significance for them.

The peak is covered by rainforest and is home to a number of endemic species.

Thornton Peak is one of only three mountain tops that are home to the cinereus ringtail possum.
