Perdicinae is a subfamily of birds in the pheasant family, Phasianidae, regrouping the partridges, Old World quails, and francolins. Although this subfamily was considered monophyletic and separated from the pheasants, tragopans, junglefowls, and peafowls (Phasianinae) till the early 1990s, molecular phylogenies have shown that these two subfamilies actually constitute only one lineage. For example, some partridges (Perdix genus) are more closely affiliated to pheasants, whereas Old World quails and partridges from the Alectoris genus are closer to junglefowls.
