Camden Sound is a relatively wide body of water in the Indian Ocean located in the Kimberley region of Western Australia. The Sound is bounded by the Bonaparte Archipelago to the north-east, the Buccaneer Archipelago to the south-west, and Montgomery Reef (the eastern extent of Collier Bay) to the south.
The Sound is an important area for a number of marine animals, in particular as a breeding ground for various species of whales, and is home to the world's largest population of humpback whales. The Lalang-garram / Camden Sound Marine Park is jointly managed by the Government of Western Australia's Department of Biodiversity, Conservation and Attractions. The marine park lies about 300 km (190 mi) north-east of Broome, and is the second largest marine park in Western Australia after Shark Bay. As of 2020[update], there is a plan to include this and three other nearby marine parks into one large marine park called Lalang-gaddam Marine Park (formerly named Great Kimberley Marine Park).
