Boeing Creek is a stream in the U.S. state of Washington, located in the city of Shoreline, just north of Seattle. It is about 1.6 miles (2.6 km) long and empties into Puget Sound. The creek is heavily modified along its course, and in many places has been diverted into culverts. The watershed of Boeing Creek is about 11.2 square miles (29 km2) in size, with two main tributaries aside from the mainstem. The creek takes its name from William Boeing, who built a mansion along the creek in 1913.
