State Route 243 (SR 243) is a state highway in Grant County, Washington. It travels north–south along the Columbia River for 28 miles (45 km), connecting SR 24 at the Vernita Bridge to SR 26 near Vantage. The highway travels through a predominantly rural and desert area, serving two hydroelectric dams and the communities of Desert Aire, Mattawa, and Beverly.

The highway was established as a branch of Secondary State Highway 7C (SSH 7C) in 1957, to be built uphill from the reservoir of the new Priest Rapids Dam. Construction was completed in the early 1960s and it was re-designated as SR 243 during the 1964 state highway renumbering.
