The white-naped xenopsaris (Xenopsaris albinucha) is a bird in the family Tityridae found in the South American countries of Venezuela, Brazil, Bolivia, Paraguay, Uruguay and Argentina. It lives in open woodland and other open forest habitats, and is mostly sedentary, though some populations may be migratory. The only species in its genus, it is closely related to becards and tityras, and was thought to be either a tyrant-flycatcher or cotinga before it was placed in the Tityridae family. The bird is 12.5 to 13 cm (4.9–5.1 in) in length, with whitish undersides, a black crown and grey-brown upperparts. The sexes are similar in appearance, though the females have duller upperparts. It feeds on insects in the foliage of trees and bushes, and sometimes on the ground. In a simple cup nest in the fork of a tree, both parents incubate the eggs and help feed the chicks. After the chicks have fledged, the parents may divide the brood, each helping one or two chicks. The species is not common and little is known about it, but it is not in danger of extinction.
