Camponotus hyatti is a species of carpenter ant. The species is native to the northern Pacific coast, from Oregon to the Baja California Peninsula. The species is characterized by its five-toothed mandibles and the smooth, shiny appearance of its clypeus, as well as a pronounced metanotal groove, lending the basal surface of the propodeum a distinct convex appearance. It commonly nests in sagebrush, Yucca, manzanita, and oak.
