State Route 900 (SR 900) is a 16.20-mile-long (26.07 km) state highway serving suburban King County, Washington. It travels east from an interchange with Interstate 5 (I-5) in northern Tukwila through the city of Renton and into the Issaquah Alps to reach the city of Issaquah, where the highway ends at an interchange with I-90.

SR 900 begins as an extension of Martin Luther King Jr. Way South at an intersection with Boeing Access Road, east of its interchange with I-5 under an elevated section of the Central Link light rail line, in the Allentown neighborhood of northern Tukwila. The four-lane highway splits at a basketweave interchange with I-5, with the southbound lanes of SR 900 traveling over the freeway twice. The roadway continues southeast into Skyway whilst parallel to I-5 and the BNSF South Seattle railyard. SR 900 turns east and becomes Sunset Boulevard as it enters Renton, following the Black River and a BNSF branch railroad, to an intersection with SR 167 at Rainier Avenue.
