Pheasants (or Phasianinae (Horsfield, 1821)) is subfamily of Phasianidae in the order Galliformes.

Pheasants are characterised by strong sexual dimorphism, males being highly ornate with bright colours and adornments such as wattles and long tails. Males are usually larger than females and have longer tails. Males play no part in rearing the young. Pheasants typically eat seeds and some insects.
