Xanthocarpia is a genus of mostly crustose lichens in the family Teloschistaceae.

The genus was originally circumscribed in 1859 by Abramo Bartolommeo Massalongo and Giuseppe De Notaris, with Xanthocarpia ochracea as the type species.

[2] Xanthocarpia has a thallus that is either crust-like (crustose) or like a shield or plate attached on the lower surface at a single central point (peltate).

Pycnidia can be present or absent; the conidia have a bacilliform to narrowly ellipsoid shape.

Several are found in southeastern Europe, with a collective distribution extending from the Mediterranean to the Arctic.
