The bare-headed laughingthrush (Melanocichla calva) is a species of bird in the Old World babbler family Timaliidae. It is endemic to highland forests at elevations of 750–1,800 m (2,460–5,910 ft) in the mountain ranges of north-central Borneo, along with some outlying peaks. It is 25–26 cm (9.8–10.2 in) long, with both sexes similar in appearance. The head is brownish to greenish yellow and featherless. The area along the lower mandible has a bluish tinge. The rest of the body is dull blackish-brown tinged with grey. Juveniles have more feathers on the head, extending from the forehead to the crown.

Described by the British ornithologist Richard Bowdler Sharpe in 1888, the bare-headed laughingthrush was then treated as a subspecies of the black laughingthrush from 1935 to 2006, when it was restored to full species status. It feeds on insects such as crickets, cicadas, and ants in dense columns of vegetation formed by vines growing around trees. Although it is classified as being of least concern by the International Union for Conservation of Nature, it is threatened by habitat destruction and fragmentation and its population is thought to be decreasing.
