The Maugean skate or Port Davey skate (Dipturus maugeanus, alternatively Zearaja maugeana) is an endangered species of fish in the family Rajidae. Also known as the 'thylacine of the sea', it is endemic to Tasmania, only found in the brackish estuarine waters of Macquarie Harbour and Bathurst Harbour. The species was discovered in 1988 by Dr Graham Edgar. It was named in honour of René Maugé, a zoologist on the Baudin expedition to Australia, who died in Tasmania in 1802.

The skate is recognised as one of the Gondwana-era natural values of Tasmania's Wilderness World Heritage Area (TWWHA) . Its potential extinction carries global significance.
