The Galiano and Valdes expedition of 1792 charted this bay as "Enseñada del Engano" (Gulf of Deception), presumably because they had run into shallow water.

The US Coast Survey named this "Mud Bay" in 1855, but re-labelled it "Boundary Bay" on the second and subsequent editions of their chart. So-named because it is intersected by the International Boundary.
