Mukilteo Light, Wooden lighthouse in Mukilteo, US.

Mukilteo Light is an octagonal wooden tower built in 1905–1906 to a Carl Leick design, standing on the east side of Possession Sound. The 8-metre tower is topped by a fixed fourth-order Fresnel lens made in France in 1852 and installed in 1927. Two Victorian-style keeper's houses, a fog-signal building, a well, a windmill and a water tank once formed the complex, now part of Mukilteo Lighthouse Park.

Congress allocated $22,000 on 9 January 1903 to build a light for the growing port of Everett. Construction to Carl Leick's design began on 30 June 1905, and the light was commissioned on 1 March 1906, fitted with a fourth-order Fresnel lens made in France in 1852. The lens was replaced in 1927, the station was automated in 1979, and the Coast Guard transferred it to the City of Mukilteo on 19 August 2001.

The name Mukilteo comes from a local Native American word meaning "good camping ground", as the site served as a winter camp for indigenous people. The lighthouse is maintained by the Mukilteo Historical Society, which cares for the tower and runs museum exhibits in the keeper's quarters.

The grounds and interior are open to the public as part of Mukilteo Lighthouse Park, and the Mukilteo Historical Society maintains the tower and its museum exhibits. The two Victorian-style keeper's homes stand on the same property, so the tower, houses and waterfront can be seen on one walk.

The structure retains its original fourth-order Fresnel lens installed in 1927, making it a rare example of a functioning historical navigation aid still in active service today. This vintage optics mechanism continues to operate and guide passing maritime traffic daily.
