The drongos are a subfamily of small passerine birds of the Old World tropics in the family Dicruridae. This family originally included only the genus Dicrurus (subfamily Dicrurinae) but Christidis and Boles (2007) expand the family to include the subfamilies Rhipidurinae (Australasian fantails), Monarchinae ( monarchs and paradise flycatchers) and Grallininae (magpie-larks).
