The Mindanao Wrinkled Hornbill (Aceros leucocephalus), also known as the Writhed Hornbill, is a species of hornbill in the Bucerotidae family. It is endemic to humid forests on the Philippine islands of Mindanao, Dinagat and Camiguin Sur. It formerly included the Rufous-headed Hornbill as a subspecies, but unlike that species, both sexes of the Mindanao Wrinkled Hornbill have orange-red throat and ocular skin.

The Mindanao Wrinkled Hornbill is threatened by habitat loss and hunting.
