The barn owls (Tyto species, particularly Tyto alba) are the most widely distributed group of owls in the world. They are medium-sized owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. The term may be used to describe:

  • The whole family Tytonidae, though this also includes the bay owls in the genus Phodilus
    • Tyto, the largest genus of birds in Tytonidae, and particularly these species in that genus:
      • Three species that are sometimes considered to be a single species known as barn owl or common barn owl:
      • Andaman masked owl Tyto deroepstorffi endemic to the southern Andaman Islands
      • New Caledonian barn owl Tyto letocarti, extinct, from the island of New Caledonia in Melanesia
