List of Olmsted parks in Seattle
In 1903, commissioned by the city of Seattle, Washington, the Olmsted Brothers landscape architects planned many of the parks in the City of Seattle as part of a comprehensive plan to create a greenbelt throughout the city.  The planning continued in several phases, culminating in the final Olmsted-planned park, Washington Park Arboretum in 1936.

The existing Seattle Parks and Recreation system has been described as "one of the best-preserved Olmsted park systems in the country". In 2016, the Olmsted parks system was added to the National Register of Historic Places as a multiple property submission.
