This genus was created by George Robert Gray, who suggested taking Campephilus principalis as the type for the genus. The name Campephilus means "lover of grubs" - an allusion to the diet of these birds, many of which feed on the larvae of wood-boring beetles. Contrary to long-held opinion, their closest relatives are not the large black Dryocopus woodpeckers: instead, they are related to the Chrysocolaptes flamebacks from Southeast Asia (Benz et al., 2006).
The English names ivory-billed woodpecker or ivorybill are sometimes used to refer to members of this genus, though more these are used specifically for Campephilus principalis.
