Wyndham is the northernmost town in the Kimberley region of Western Australia, 3,315 kilometres (2,060 mi) northeast of Perth via the Great Northern Highway. It was established in 1886 to service a new goldfield at Halls Creek, and it is now a port and service centre for the east Kimberley with a population of 941 as of the 2021 census. Aboriginal and Torres Strait Islander people make up 54% of the population. Wyndham comprises two areas - the original town site at Wyndham Port situated on Cambridge Gulf, and 5 kilometres (3.1 mi) by road to the south, the Three Mile area with the residential and shopping area for the port, also founded in 1886. Wyndham is part of the Shire of Wyndham-East Kimberley.

The Kimberley is the northernmost of the nine regions of Western Australia. It is bordered on the west by the Indian Ocean, on the north by the Timor Sea, on the south by the Great Sandy and Tanami deserts in the region of the Pilbara, and on the east by the Northern Territory.
