Port Gamble is an unincorporated community and census-designated place (CDP) on the northwestern shore of the Kitsap Peninsula in Kitsap County, Washington, United States. It is also a small, eponymous bay, along which the community lies, near the entrance to Hood Canal. The unincorporated communities of Port Gamble and Little Boston, part of Kitsap County, lie on either side of the mouth of this bay. The Port Gamble Historic District, a U.S. National Historic Landmark, covers one of the nation's best-preserved western lumber towns. The population was 916 at the 2010 census.
The community of Port Gamble has a wide range of shops from antiques to a tea shop to an old-fashioned general store. It is a popular tourist destination, due to its location near Bremerton, Port Townsend, Bainbridge Island, and Seattle and its downtown. Port Gamble is also home to the grave of Gustave Englebrecht, the first U.S. Navy sailor to die in the Pacific.
