<p>Papillomaviruses are small circular DNA viruses that infect epithelial cells of their hosts. Avian papillomaviruses are poorly sampled/documented compared to those infecting humans. We used a viral metagenomic approach to identify viruses from the oral swab taken from a deceased south polar skua (<i>Stercorarius maccormicki</i>) found at Cape Royds, Ross Island, Antarctica in late 2024. We identified three papillomaviruses and determined their complete genomes, Stercorarius maccormicki papillomavirus (SmacPV) 1-3. SmacPV1 is the most divergent of the three SmacPVs, sharing 62% genome-wide pairwise identity to SmacPV2 and SmacPV3 and &lt;63.5% to other avian papillomaviruses. The genomes of SmacPV2 and SmacPV3 represent two new papillomavirus types sharing 82.4% genome-wide pairwise identity with each other and &lt;72% to other papillomaviruses. SmacPV2 and SmacPV3 phylogenetically cluster with sequences of the Rissa tridactyla papillomavirus 1 from black-legged kittiwake (<i>Rissa tridactyla</i>), Larus smithsonianus papillomavirus 1 from American herring gull (<i>Larus smithsonianus</i>) and Fratercula arctica papillomavirus 1 from Atlantic puffin (<i>Fratercula arctica</i>), and they collectively represent a new papillomavirus species. These are the first papillomaviruses to be identified in <i>Stercorarius</i> spp<i>.</i> and add to the handful of known papillomaviruses in identified avian species. We also expand the known host range of papillomaviruses in Antarctic animals, which previously included Adélie penguins (<i>Pygoscelis adeliae</i>), Weddell seals (<i>Leptonychotes weddellii</i>), Antarctic fur seals (<i>Arctocephalus gazella</i>), leopard seals (<i>Hydrurga leptonyx</i>) and emerald notothen (<i>Trematomus bernacchii</i>).</p>
