The Marymoor Prehistoric Indian Site is the site of an archaeological dig in Marymoor Park, Redmond, Washington. After King County bought the property in 1962, the site was one of four sites in the park considered for excavation. The dig began in 1964, and continued for four years. Many of the items were exhibited in the Marymoor Museum, which was at the park until King County evicted it 2002. Other items were sent to the Burke Museum at the University of Washington.
