The black-headed antthrush (Formicarius nigricapillus) is a species of bird in the family Formicariidae. It is found in Colombia, Costa Rica, Ecuador, and Panama. The black-headed antthrush has two subspecies, the nominate F. n. nigricapillus (Ridgway, 1893) and F. n. destructus (Hartert, EJO, 1898).

The black-headed antthrush is about 18 cm (7.1 in) long; four individuals weighed 58 to 68 g (2.0 to 2.4 oz). The sexes have the same plumage. Adults of the nominate subspecies have a dark dusky brown to blackish crown. Their face and throat are black with a ring of bluish white bare skin around the eye. Their back, rump, and wings are dark chestnut-brown, their uppertail coverts dark rufescent brown, and their tail black. Their flight feathers have dusky inner edges and a wide cinnamon band at the base. Their upper breast is blackish gray, their belly gray, and their undertail coverts rufous. They have a brown iris, a black bill, and dusky brown legs and feet. Subspecies F. n. destructus has darker and less reddish-tinged upperparts than the nominate.
