State Route 516 (SR 516) is a 16.49-mile-long (26.54 km) state highway in the U.S. state of Washington, serving communities in southern King County. The highway travels east as the Kent-Des Moines Road and the Kent-Kangley Road from a concurrency with SR 509 in Des Moines through Kent and Covington to an intersection with SR 169 in Maple Valley. SR 516, designated as part of the National Highway System within Kent, intersects three major freeways in the area: Interstate 5 (I-5) in western Kent, SR 167 in downtown Kent, and SR 18 in Covington. The roadway, built in the 1890s, was codified in 1937 as Secondary State Highway 1K (SSH 1K) from Des Moines to Kent and SSH 5A from Kent to Maple Valley. The two highways were combined during the 1964 highway renumbering to form SR 516 on its current route.

SR 516 begins in Des Moines at Marine View Drive as SR 509 turns north towards Burien near the East Passage of Puget Sound. The two concurrent highways travel east on the Kent-Des Moines Road past Highline Community College and Mount Rainier High School to an intersection with SR 99 in western Kent, where SR 509 turns south towards Tacoma. Shortly thereafter, SR 516 intersects I-5 at a partial cloverleaf interchange and continues east onto a four-lane divided highway over the Green River and its pedestrian and bicycle trail into downtown Kent. The highway serves as the southern terminus of SR 181 before intersecting SR 167 in a diamond interchange at the western edge of downtown Kent. SR 516 shifts south onto Willis Street and crosses the Interurban Trail and a BNSF rail line before turning north onto Central Avenue and east onto Smith Street near Kent Station. The highway travels southeast along Mill Creek onto the Kent-Kangley Road and serves as the southern terminus of SR 515 at Kent-Meridian High School before leaving Kent for Covington. SR 516 passes Lake Meridian as 272nd Street and intersects SR 18 at a diamond interchange located in Covington. The highway continues east past Pipe Lake and into Maple Valley before crossing the Cedar to Green River Trail and ending at an intersection with SR 169.
