Kingston (formerly Appletree Cove[3]) is an unincorporated community and census-designated place (CDP) in Kitsap County, Washington, United States.

[4] Kingston is along the shores of Appletree Cove and Puget Sound, and is home to a major Washington State Ferry terminal linking it to Edmonds.

[6] Founded in 1853 by Benjamin Bannister, the community was originally known as "Appletree Cove".

King built many small buildings and shacks along the shore for his men and animals.

Calkins had drawings and designs for a giant hotel on the waterfront, with a boat launch, a church on the hill, and a college.

After Calkins and Brierly platted the town, a lower than expected number of people showed up to settle there.

Kingston has a Washington State Ferries terminal for auto/passenger service to Edmonds.

[8] In September 2012, due to financial losses, the Port of Kingston discontinued its SoundRunner Kingston–Seattle passenger-only system.

[11] The new vessel is 38 feet (12 m) long, can travel at 36 knots (67 km/h), and can pump 2,700 gallons per minute.

The Department of Homeland Security has provided small ports with grants to equip themselves with modern fireboats, with sealed cabins, that can also help counter other threats, like oil spills, or attacks by chemical or biological weapons.

Kitsap Fast Ferries began service from Kingston to Seattle in November 2018.
