U.S. Route 99 marker

U.S. Route 99 (US 99) was a main north–south United States Numbered Highway on the West Coast of the United States until 1964, running from Calexico, California, on the US–Mexico border to Blaine, Washington, on the U.S.-Canada border. It was assigned in 1926 and existed until it was replaced for the most part by Interstate 5. Known also as the "Golden State Highway" and "The Main Street of California", US 99 was important throughout much of the 1930s as a route for Dust Bowl immigrant farm workers to traverse the state. Large portions are now California's State Route 99 (SR 99), Oregon Route 99, 99W, 99E and Washington's SR 99. The highway connected to British Columbia Highway 99 at the Canada–US border.

The former route of U.S. Route 99 in Oregon mostly follows routes currently signed as Oregon Route 99, 99E, and 99W. The primary exception is from the California–Oregon state border north to Ashland, Oregon, where U.S. 99 is currently named Old Highway 99 S from the state border to Exit 6 of Interstate 5. The former route is coterminous with Interstate 5 from Exit 6 to the junction of Oregon Route 99 in Ashland.
