Pierce County is a county in the U.S. state of Washington. As of the 2020 census, the population was 921,130, and was estimated to be 946,288 in 2025, making it the second-most populous county in Washington, behind King County, and the 60th-most populous in the United States. The county seat and largest city is Tacoma, Formed out of Thurston County on December 22, 1852, by the legislature of Oregon Territory, it was named for U.S. President Franklin Pierce. Pierce County is in the Seattle metropolitan area.

The area was originally home to the present-day Nisqually, Puyallup, Squaxin, Steilacoom, and Muckleshoot tribes. The majority of Puyallup villages were situated in proximity to the area that would eventually develop into Tacoma, while Nisqually settlements were primarily located in what is now southern Pierce County. The tribes had two main routes: a northern path traversing Naches Pass and a southern route following the Mashel River, which connected them to Eastern Washington tribes. Trade networks among the region's indigenous peoples were well-established long before the arrival of white settlers. In 1792 British Captain George Vancouver and his party of explorers came via ship to the shores of the region, and named a number of sites in what would become Pierce County, i.e. Mount Rainier.
