West Seattle, a hilly district in Seattle, Washington, USA, encompasses all of Seattle west of the Duwamish River. It was incorporated as an independent city in 1902 and was annexed by Seattle in 1907. Among its attractions are its saltwater beach parks along Elliott Bay and Puget Sound: Alki Beach and Lincoln Park, among others. It is also prized for its magnificent views of the Olympic Mountains to the west and the Cascades to the east.

The highest point in Seattle is in the Gatewood neighborhood, adjacent to the aptly named High Point neighborhood of West Seattle; at 35th Avenue S.W. and S.W. Myrtle Street it is 520 feet above sea level. The hill is dominated by two huge water towers.

Alki Point is traditionally credited as the point where the Denny Party founded Seattle prior to moving across Elliott Bay. A similar landing at Alki has been reenacted annually since 1950 as part of the colorful, week-long Seafair celebration of Seattle's marine and boating interests. Seafair coincides with the much older Hi-Yu festivities in West Seattle.

There is a Washington State Ferries dock in the Fauntleroy neighborhood, with service to Vashon Island and to Southworth on the Kitsap Peninsula. A shuttle ferry also runs between Duwamish Head and downtown Seattle.
