Rollulinae is a bird subfamily containing the jungle and wood partridges. They are the most basal member of the family Phasianidae, having diverged during the late Eocene or early Oligocene, about 30-35 million years ago. ^{[1] [2]} Many taxonomists formerly placed this subfamily within the Perdicinae, but more recent studies have affirmed its existence, and it is accepted by taxonomic authorities such as the International Ornithological Congress. ^{[2] [3] [4] [5]}

Members of this family are mostly found in east and southeast Asia, along with a single basal genus containing two species endemic to two mountain ranges in Tanzania. ^[5]
