Rhyticeros is a genus of medium to large hornbills (family Bucerotidae) found in forests from Southeast Asia to the Solomons.

The order name is from Latin becerus meaning "horned like an ox" which in turn is from the Ancient Greek boukerōs which combines bous meaning "ox" with kerōs meaning "horn".
Rhyticeros Greek rhutis, rhutidos wrinkle; keros horn.
