Buceros is a genus of large Asian hornbills (family Bucerotidae).


Hornbills in the genus Buceros include some of the largest arboreal hornbills in the world, with the largest being the great hornbill. All the hornbills in this genus have a large and hollow bony casque on their upper beak that can be useful to scientists and bird watchers to recognise their age, sex and species. Their wingspan can be up to 1.8 meters (6 foot) and they have the largest wingspan out of all the hornbills.


Species included in the genus are:

The helmeted hornbill is sometimes included in this genus, but today most authorities place it in the monotypic Rhinoplax instead.
