Phillips Bay is a shallow, dynamic coastal bay on the Beaufort Sea coast within the Inuvialuit Settlement Region of Canada's western Arctic. The bay receives freshwater input from several rivers, most notably the Babbage River, which flows between the British and Barn mountains before emptying into the bay. The shoreline and nearshore areas have been undergoing significant changes, with the bay becoming notably shallower over decades, to the point where areas that once accommodated schooners in the 1950s are now too shallow for such vessels. This is a remote, pristine wilderness area characterized by its importance as a migratory corridor and subsistence fishing ground.
