The San Francisco Port of Embarkation (SFPOE) was a United States Army command responsible for movement of supplies and troops to and from the Pacific during World War II with extensive facilities in the San Francisco area. SFPOE was established 6 May 1932 and disestablished 1 October 1955. It was originally composed of the long term Pacific terminal at Fort Mason that had been the home port and terminal for the Pacific Army Transport Service ships. That facility was far too limited to serve the requirements of a full port of embarkation. In 1940 the port began expansion to include Army owned and leased facilities throughout the San Francisco Bay area and for a time sub ports at Seattle and Los Angeles. Those eventually became separate commands as the and Los Angeles Port of Embarkation.
