The Golden Masked-owl (Tyto aurantia) is a barn-owl endemic to the island of New Britain, Papua New Guinea. It is also known as New Britain Barn-owl, New Britain Masked-owl, Bismarck Owl and Bismarck Masked-owl.

As with other tropical barn-owls, it is difficult to spot in the wild and therefore poorly studied. It is likely to be a lowland forest species.

Given the paucity of reliable information, it was for some time classified as a data deficient species by the IUCN. When its status could finally be evaluated properly, earlier assessments were found to be correct, and it is once again listed as a Vulnerable species in the 2008 redlist.
