Megaceryle is a genus of very large kingfishers. They have a wide distribution in the Americas, Africa, and Southeast Asia.
The genus was erected by German naturalist Johann Jakob Kaup in 1848. The type species is a subspecies of the crested kingfisher, Megaceryle lugubris guttulata. Megaceryle is from the Ancient Greek megas, "great", and the existing genus Ceryle.
