Grallina is a genus composed of two species of passerine bird native to Australia and New Guinea. It is a member of a group of birds termed monarch flycatchers. This group is considered either as a subfamily Monarchinae, together with the fantails as part of the drongo family  Dicruridae, or as a family Monarchidae in its own right. More broadly, they belong to the Corvida parvorder comprising many tropical and Australian passerines including pardalotes, fairy-wrens and honeyeaters as well as crows.
