Longbranch is an unincorporated community and census-designated place in Pierce County, Washington, located on the Key Peninsula along the shore of Filucy Bay, between Pitt Passage and Balch Passage in southern Puget Sound. The Key Peninsula is the southernmost extension of the larger Kitsap Peninsula, a finger of land whose shoreline is laced with inlets, passages, and forested bluffs. Longbranch occupies a sheltered stretch of this coastline, and its character is shaped almost entirely by the water. The community is primarily residential, with a small marina, a church, and a community center serving as its civic anchors. Homes are dispersed across wooded and waterfront parcels rather than arranged in a conventional town center, giving Longbranch a quiet, spread-out feel. Residents are drawn to the area for its solitude, water access, and connection to the natural landscape of southern Puget Sound, where tides, marine life, and shoreline views define the daily backdrop. Recreation is anchored by two nearby state parks. Penrose Point State Park, just to the north, protects more than two miles of saltwater shoreline along with hiking, biking, and nature trails. Joemma Beach State Park, on the peninsula's southwestern shore, is a 122-acre park with 3,000 feet of saltwater shoreline, picnic and camping areas, and facilities for boating, fishing, and crabbing. These parks, together with the bay itself, make the area a destination for water-oriented living. Longbranch is served by the Peninsula School District, and residents rely on the Key Peninsula's small communities—Key Center, Vaughn, and Lakebay—for groceries and services, with Tacoma reachable to the east across the Purdy bridge. The community suits those seeking a secluded, waterfront lifestyle within commuting distance of the Puget Sound region's larger cities.
