Spanaway is a large, unincorporated community in southern Pierce County, Washington, positioned between the city of Tacoma to the north and Joint Base Lewis-McChord (JBLM) to the south. Its name comes from Spanaway Lake, a natural lake that has long been the community's recreational centerpiece and gathering point. Because it is not an incorporated city, Spanaway is governed directly by Pierce County, and it functions as a broad residential area rather than a single downtown-centered town. With a population of roughly 35,500, it is one of the more populous unincorporated places in the state. The community's identity is closely tied to Joint Base Lewis-McChord, one of the largest military installations on the West Coast. Spanaway sits immediately adjacent to the base's northern edge, and a significant share of its residents are active-duty service members, veterans, and military families. This presence shapes local schools, retail, and the steady demand for housing across the area. The base itself combines the former Fort Lewis and McChord Air Force Base, making Spanaway a natural residential choice for those assigned there. Development in Spanaway spreads across several distinct corridors. Older residential neighborhoods line Pacific Avenue (State Route 7), the historic north-south spine of the community, while newer subdivisions have expanded eastward toward the Frederickson industrial corridor and southward toward the base. Spanaway Lake and its surrounding parks offer fishing, boating, and shoreline recreation close to home, and commercial development clusters along the major roadways. Public school students in Spanaway attend the Bethel School District, which is headquartered in the community and operates campuses across the greater south Pierce County area. With Tacoma a short drive north, Joint Base Lewis-McChord at its doorstep, and Seattle reachable via the broader highway network, Spanaway serves as a residential base for people working throughout the South Sound.
