Port Douglas is a coastal town and locality in the Shire of Douglas, Queensland, Australia, approximately 60 km north of Cairns. In the 2021 census, Port Douglas had a population of 5,582 people. The town's population can often double, however, with the influx of tourists during the peak tourism season May–September. Port Douglas is named in honour of former Premier of Queensland, John Douglas. Port Douglas developed quickly based on the mining industry. Other parts of the area were established with timber cutting occurring in the area surrounding the Daintree River and with settlement starting to occur on lots around the Mossman River by 1880.
Previous names for the town included Terrigal, Island Point, Port Owen and Salisbury. The town is situated adjacent to two World Heritage areas, the Great Barrier Reef and the Daintree Rainforest.
