Luna Park, Amusement park at Duwamish Head in Seattle, United States.

Luna Park was an amusement park built on pilings over Elliott Bay at Duwamish Head in West Seattle. Its wooden boardwalk extended over the water, and the site included a large Natatorium with cream-colored walls, red roofs, a central square tower with arched windows, and a long red barrel-vaulted roof with glass panels over its left section.

Charles I. D. Looff designed and oversaw the construction of the park in 1906, envisioning it as a recreation destination. It opened in 1907 and closed in 1913.

Luna Park took its name from Coney Island's Luna Park, and its nightly bulb outlines made it visible for miles, promoted as a safe evening destination for women and children. Two theatres, the Dreamland and the Trocadero, staged vaudeville, the Trocadero a new play each week, alongside daily acts such as Uncle Hiram the clown and Don Carlo's Trained Monkey and Dog Circus.

The park was located at a waterfront site that made it easily accessible by boat across the bay for visitors seeking water and land-based entertainment. Guests could move between different rides and pools to enjoy a full day of activities.

In 1908, a pilot named L. Guy Mecklem launched Seattle's first manned flight from this location, racing against two automobiles in a ten-mile competition. This early flight attempt marked a rare moment when aviation and land transport were directly compared.
