The Broad-billed Fairywren (Chenorhamphus grayi) is a species of bird in the Maluridae family. It is found in Indonesia and Papua New Guinea.
Its natural habitat is subtropical or tropical moist lowland forests.
Malurus grayi and M. campbelli (Campbell's Fairywren) (Sibley and Monroe 1990, 1993) have been lumped into M. grayi following Beehler et al. (1986), Coates (1990) and Vuilleumier et al. (1992).
A 2011 analysis by Amy Driskell and colleagues of mitochondrial and nuclear DNA showed high divergence between the two subspecies and has recommended they be resplit into separate species. It also found them to lie in a clade with the two other monospecific New Guinea genera and not with the other species of Malurus. Hence they recommend reclassifying them within the genus Chenorhamphus.
