Puget Sound is an arm of the Pacific Ocean, connected to the rest of the Pacific by the Strait of Juan de Fuca, in the Pacific Northwest of the United States. It is a very large salt water estuary fed by highly seasonal freshwater from the Olympic and Cascade Mountain watersheds. It extends from the southern end of Whidbey Island to Olympia, Washington.

The urban region designated the Puget Sound Region is centered on Seattle, Washington, and consists of nine counties, two urban center cities and four satellite cities making up what has been dubbed the "Pugetropolis". Both urban core cities have large industrial areas and seaports plus a high-rise central business district. The satellite cities are primarily suburban, featuring a small downtown core and a small industrial area or port. The suburbs consist mostly of residences, strip malls, and shopping centers. The region is also home to numerous ports. The two largest and busiest are the Port of Seattle and Port of Tacoma, which, if combined, comprise the second largest container port in North America after Los Angeles/Long Beach. The Port of Vancouver, the largest Canadian port, sits on the northern end of the Greater Puget Sound Area. A unique state-run ferry system, the Washington State Ferries, connects the larger islands to the Washington mainland, as well as both sides of the sound, allowing cars and people to move about the greater Puget Sound region.
