Walcott Inlet is an estuary located in the Kimberley region of Western Australia. It flows into Collier Bay, in the Indian Ocean, via a narrow gap known as Yule Entrance.
The inlet was named on 19 June 1865 by Trevarton Charles Sholl after Stephen Walcott, Commissioner of the Government Emigration Board, while on an exploratory expedition from the short-lived Camden Harbor settlement (in Camden Sound).
The inlet is 66 km in length, with a width of 9 km and covering an area of 257 km2. It is tide-dominated, and in nearly pristine condition with a catchment area of 12,732 square kilometres. The entry to the inlet, known as Yule Entrance, is 9 km in length and as little as 450 m wide. The mean tidal range at the mouth is 6.52 m, but can reach 11 metres, leading to turbulence, strong tidal flows and whirlpools.
