Carkeek Park is a 216 acres (87 ha) park located in the Broadview neighborhood of Seattle, Washington. The park contains Piper Orchard, Pipers Creek (and its tributaries Venema Creek and Mohlendorph Creek), play and picnic areas, picnic shelters, and hiking trails. A pedestrian bridge across the main lines of the BNSF Railway connects to the Carkeek Park sand beach on Puget Sound. Park program activities are largely out of the Carkeek Park Environmental Learning Center.
Seattle's first park to be called "Carkeek Park" was on Pontiac Bay, Lake Washington (1918–1926), now site of Magnuson Park. The original was a gift of Mr. and Mrs. Morgan J. Carkeek, prominent builder and contractor in Seattle, Oregon, and Victoria, B.C. The original was displaced by a Naval Air Station. Morgan Carkeek offered the proceeds of his sale to the City for another park.
Most of the existing site was purchased by the City of Seattle in the later 1920s, with 20% donated by Carkeek, following citizen petition over vigorous City opposition. The park went through a few themes over years, from outdoor performance venue, to farm for zoo animal feed, to pasturage rental, to park with WPA Civilian Conservation Corps construction (1933-–36, removed in 1938), to U.S. Army camp (just in 1942), to sewage treatment plant (over vigorous opposition by neighborhoods groups). Bond funds in the late 1940s allowed reconstruction of park facilities, including a planned large equestrian academy and concession to reduce chronic rowdyism in the park, but a tight city budget in spite of generous donations forced indefinite postponement. An archery field was built (c. 1955), and closed when it was moved to Magnuson Park in August 1985. Treated sewage outfall ended in the early 1960s with closure of the treatment plant and replacement with a Metro sewage pumping station near the parking lot for the beach.
Additional property was donated in 1953 but could not be incorporated until the city could raise funds to buy the intervening ravine in 1973.
