The Turkeys, Grouse, Pheasants & Partridges (Phasianidae) is a large family of 183 mainly terrestrial, ground living speciesspecies.

They are variable in size and ranging from 43 g, in the case of the Asian Blue Quail, to 6 kg in the case of the Indian Peafowl. There is generally sexual dimorphism in size, with males tending to be larger than females. They are generally plump, with broad relatively short wings and strong legs. Many have a spur on their legs, a feature shared with guineafowl. The bill is short and generally strong, particularly in species that dig in order to obtain food. Males of the larger species often have brightly coloured plumage as well as facial ornamentations such as wattles or crests.

Several species of pheasant and partridge are extremely important to humans. The Red Junglefowl of Southeast Asia is the wild ancestor of the domesticated chicken, the most important bird in agriculture. Ring-necked Pheasants, several partridge and quail species and some francolins have been widely introduced and managed as game birds for hunting. Several species are threatened by human activities.

The family can be divided into four subfamilies:
-Asiatic Partridges (Rollulinae)
-Peacock-Pheasants (Polyplectroninae)
-Fowl, Francolins, Partridges, Quail (Gallinae)
-Pheasants, Grouse, Turkeys (Phasianinae)
