Westport is a city in Grays Harbor County, Washington, United States. The city's population was 2,099 at the 2010 census.
Westport is located on a peninsula on the south side of the entrance to Grays Harbor from the Pacific Ocean. The public Westport Marina is the largest marina on the outer coast of the United States's Pacific Northwest. The marina is home to a large commercial fishing fleet and several recreational charter fishing vessels. A summer-only passenger ferry, discontinued in 2008, previously connected the town to Ocean Shores, across the mouth of the harbor to the north.
Westport was officially incorporated on June 26, 1914. Names for the area in the past include Peterson's Point, Chehalis City and Ft. Chehalis. The latter name is for a fort established in 1860 before the town was founded. The area was used regularly during the summer by local Native American tribes (most likely the Shoalwater Bay tribe) before Thomas Barker Speake and his family arrived early in the summer of 1857. Westport is also the home to a station for the US Coast Guard.
