State Route 121 is a state road in Thurston County, Washington, United States. Though it is numbered as an auxiliary route of US 12 and formerly connected to that road,[1], it is separated from US 12 because Route 121 was truncated to I-5 on 1 April 1992[1]. The main purpose of the route is to serve several towns south of Olympia and provide access to Millersylvania State Park.
From the 1964 renumbering until 1967, SR 121 was State Route 801, a spur of the former State Route 8 from Rochester to Interstate 5 near Maytown. When SR 8 became a portion of U.S. Route 12 in 1967, SR 801 was renumbered to SR 121.
