Commencement Bay is a
bay of
Puget Sound in the
U.S. state of
Washington. The city of
Tacoma is located on the bay, with the
Port of Tacoma occupying the southeastern end. A line drawn from
Point Defiance in the southwest to
Browns Point in the northeast serves to mark the generally accepted division between the bay and the open sound. Commencement Bay has become home to one of the most active commercial ports in the world. The
Port of Tacoma is the main port facility.
