King Sound (left) is an inlet of the Indian Ocean, in northern Western Australia, measuring 90 miles by 35 miles (145 km by 56 km). Its entrance is flanked by Cape Leveque to the west and the four island clusters of the Buccaneer Archipelago in Yampi Sound to the east. A peninsula that divides the inner section of the inlet has the port of Derby on its western shore.
The mouths of the Fitzroy, Meda, Lennard, May, and Robinson rivers are along its shores, releasing tan colored sediments into the sound and clouding its waters. A 35-foot (11-metre) tidal range poses a challenge to navigators, as does the presence of many shoals.
