State Route 823 (SR 823) is a state highway in Yakima County, Washington, United States. It runs for 5.6 miles (9.0 km) from an interchange with U.S. Route 12 (US 12) and through the city of Selah to a junction with SR 821. A portion of the highway runs in the median of Interstate 82 (I-82), its parent route, as it crosses the Naches River.

SR 823 was established by the state government in 1984, running from I-82 to downtown Selah. It replaced earlier city and county roads built in the late 19th century and rebuilt several times in the early 20th century alongside an interurban railway. The north half of the route was built by the county in the 1970s and added to SR 823 in 1991. The section through downtown Selah was later rerouted onto a truck bypass built by the state in 2011, eliminating an extra turn in the route.
