Casco Bay is an inlet of the Gulf of Maine on the coast of Maine in the United States. The National Oceanic and Atmospheric Administration's chart for Casco Bay marks the dividing line between the bay and the Gulf of Maine as running from Bald Head on Cape Small in Phippsburg west-southwest to Dyer Point in Cape Elizabeth. The city of Portland and the Port of Portland are on Casco Bay's western edge.[1]
