Manchester is an unincorporated community and census-designated place (CDP) in Kitsap County, Washington, United States.

[3] Manchester is located on the Puget Sound approximately 10 miles from downtown Seattle, and is adjacent to county seat Port Orchard to its east.

[4] It is small in size but is home to a Kitsap Regional Library (KRL) branch, a post office, an elementary school, and a beachfront park to serve its residents.

After a permanent dock was built in 1908, regular steamboat service connected Manchester to nearby communities like Colby, Southworth, and Harper, and to Seattle across the water.

From 1925 to 1936, a ferry route across Puget Sound connected Manchester with Alki Point in West Seattle.

While the Navy still owns most of the original land, some of the property is now occupied by Manchester State Park as well as by Environmental Protection Agency and NOAA labs.

[9] It is on the west side of Puget Sound from Rich Passage in the north to Yukon Harbor in the south.

This region experiences warm (but not hot) and dry summers, with the highest average temperatures in late July and early August, at around 77 °F.

Manchester generally experiences both mild summers and winters, with average annual snowfall of around 3 inches.

[12] Manchester also has a library, which in 2021 underwent renovations to update the interior and expand the building itself, including the addition of solar panels to offset future energy costs.

[13] Volunteer group Friends of the Manchester Library hosts a variety of fundraising and community events throughout the year.

These events range from Fathers' Day salmon bakes and a Christmas tree lighting to summer farmers' markets and plant sales.
