State Route 24 (SR 24) is a state highway in the south-central region of Washington, in the United States. It travels 79 miles (127 km) from Yakima to Othello, across a portion of the Columbia Plateau. The highway crosses the Columbia River on the Vernita Bridge, located near the Hanford Site. SR 24 terminates to the west at an interchange with Interstate 82 (I-82) in Yakima and to the east at SR 26 in Othello.

The highway was added to the state highway system in 1937 as Secondary State Highway 11A (SSH 11A), composed of several county-built gravel roads from Yakima to Connell, with a ferry crossing at Hanford. The Hanford section of SSH 11A was closed in 1943 due to wartime activities at the Hanford Nuclear Reservation, forcing the state government to relocate the highway to the north side of the Columbia River. The new highway opened in 1961 and was supplanted by the new Vernita toll bridge in 1965. During the 1964 state highway renumbering, SR 24 replaced most of SSH 11A and was rerouted to a terminus in Othello.
