State Route 161 (SR 161) is a 36.25-mile-long (58.34 km) state highway serving Pierce and King counties in the U.S. state of Washington. The highway begins at SR 7 southwest of Eatonville and travels north as Meridian Avenue to Puyallup, becoming concurrent with SR 512 and SR 167. SR 161 continues northwest as the Enchanted Parkway to end at an intersection with SR 18 in Federal Way, west of Interstate 5 (I-5). The highway serves the communities of Graham and South Hill before reaching Puyallup and the communities of Edgewood, Milton, and Lakeland South before reaching Federal Way.

SR 161 was established during the 1964 highway renumbering, replacing three Secondary State Highways (SSHs): Secondary State Highway 5D (SSH 5D) and SSH 5G, both established in 1937, and SSH 5N, established in 1955. SSH 5D served as a connector between Federal Way and Puyallup and SSH 5G served as a connector between Puyallup and South Hill. SSH 5N connected Eatonville to South Hill and was extended south towards La Grande in 1967. SR 161 was moved onto a bypass of Puyallup in the 1980s and formed concurrencies with SR 167 and SR 512 as a result. As of 2013^[update], projects to expand the highway in Edgewood and Milton and adding new offramps at the I-5 and SR 18 interchange are in progress.
