The eastern grass owl (Tyto longimembris), also known as Chinese grass owl or Australian grass owl, is a species of owl in the family Tytonidae. They feed predominantly on small rodents.
Though some authorities consider this owl to be conspecific with the African grass owl, T. capensis, other consider it to be a valid species.
The eastern grass owl is a medium-sized owl, similar in size to the barn owl. They have dark brown or tan upper parts with pale spots. They have black and tan bars on its wings and a very pale beak, feathered legs, and dark brown eyes. Like all Tyto owls, it has a heart-shaped facial disk with brown buff and a white bordering.
