Brigade Bay is a walk-in wilderness campsite on the eastern shore of Gambier Island, located in Howe Sound off British Columbia's lower Sunshine Coast.

It sits on the north side of the island and is accessible by boat or via a rough trail that connects to Halkett Bay Marine Park.

The surrounding area offers classic coastal scenery, including views of the Sunshine Coast mountains, marine wildlife such as seals, and the working watercraft of Howe Sound.

Gambier Island as a whole is a rural retreat popular for hiking, kayaking, and boating, with Brigade Bay serving as one of several backcountry camping options alongside nearby Douglas Bay, Halkett Bay, and West Bay.
