State Route 124 (SR 124) is a state highway in Walla Walla County, Washington, United States. It spans 45 miles (72 km) from Burbank in the west to Waitsburg in the east, intersecting U.S. Route 12 (US 12) at both ends. The highway generally follows the Snake and Touchet rivers and intersects SR 125 near Prescott.

SR 124 was previously part of two state highways: Secondary State Highway 3D (SSH 3D) from Burbank to Prescott, and SSH 3E from Prescott to Waitsburg. During the 1964 state highway renumbering, sections of both highways were formed to SR 124, which was officially named Ice Harbor Road and designated as a state scenic byway by the state legislature.
