Denmark is a town in the Great Southern region of Western Australia, 423 kilometres (263 mi) south-south-east of the state capital of Perth. At the 2006 census, Denmark had a population of 2,732.
The coast line of the Denmark area was observed for the first time in 1627 by the Dutchman François Thijssen, captain of the ship 't Gulden Seepaert (The Golden Seahorse). Captain Thijssen had discovered the south coast of Australia and charted about 1,800 kilometres (1,100 mi) of it between Cape Leeuwin and the Nuyts Archipelago. Thijssen named the discovered land after Pieter Nuyts, a high employee of the Dutch East India Company, who was aboard ship as a passenger. His name lives on in Nuytsia floribunda, the Western Australian Christmas Tree.
