State Route 230 (SR 230) is a legislated, but unconstructed, state highway to be located in Adams and Whitman counties in the U.S. state of Washington. The highway would begin at a junction with concurrent highways Interstate 90 (I-90) and U.S. Route 395 (US 395) near Ritzville and travel east to an intersection with SR 23 near Ewan.
Plans for the first highway first emerged in 1943 as an extension of Primary State Highway 18 (PSH 18) to be studied after the conclusion of World War II. It was renumbered to SR 230 in 1964, but no further action was taken on constructing the highway.
