Haliastur is a genus of medium-sized diurnal birds of prey. It consists of two species of kites which form part of the subfamily Milvinae; some authorities place these species in the genus Milvus, despite clear differences in behaviour, voice and plumage.

Kite is the common name for certain birds of prey in the family Accipitridae, particularly in subfamilies Milvinae, Elaninae, and Perninae. The term is derived from Old English cȳta, possibly from the onomatopoeic Proto-Indo-European root *gū- , "screech."
