The dromedary camel or Arabian camel (Camelus dromedarius) is a large, even-toed ungulate with one hump on its back.

Its native range is unclear, but it was probably domesticated in the Arabian Peninsula about 4000 years ago. The domesticated form occurs widely in North Africa, South Asia and the Middle East. Today there are almost 13 million domesticated dromedaries. The dromedaries are beneficial as beasts of burden, and their docility and toughness compared to cattle are additional advantages. The hair is an excellent source material for woven goods.
