The chestnut-crowned gnateater (Conopophaga castaneiceps) is a species of bird in the family Conopophagidae. It is found in Colombia, Ecuador, and Peru.

The chestnut-crowned gnateater is 13 to 14 cm (5.1 to 5.5 in) long. The mean weight of seven specimens was 27.6 g (0.97 oz). The male of the nominate subspecies has brown upper parts; a gray face, throat, and chest; and orange-brown flanks and vent area. The top of the head is orange-red and there is a white tuft behind the eye. C. c. chapmani has a brighter (less brown) crown. C. c. brunneinucha's orange-red is only the forehead; it is darker overall and has a white patch on the belly. C. c. chocoensis is similar to brunneinucha but is smaller, has less gray, has a more olive tinge to the back, and more orange-red on the crown. The female's head and chest are orange-red and the belly is whitish. The white plume behind the eye is smaller than that of the male.
