"Rhyticeros" is a genus of medium to large hornbills (Bucerotidae family) found in forests from south-east Asia to the Solomons. They are sometimes included in the genus "Aceros". On the contrary, most species generally placed in "Aceros" are sometimes moved to "Rhyticeros", leaving "Aceros" as a monotypic genus only containing the Rufous-necked Hornbill.

All species generally placed in "Rhyticeros" have relatively low conspiciously wreathed casques, and a mainly dull whitish-horn bill. Both sexes have a mainly black plumage, but the head and neck of the males are white or rufous. The tail is white, except in the black-tailed Sumba Hornbill. They have conspicuous inflatable skin on the throat that is blue in all except the males of the Plain-pouched and Wreathed Hornbills, where it is yellow.
