Two highways in the U.S. state of Washington have been named State Road 1:
- State Road 1 (Washington 1905-1913), the White River-Natches Road
- State Road 1 (Washington 1923-1937), the Pacific Highway; became Primary State Highway 1 until 1970
- It has also been stated that the Cascade Wagon Road had this number,[1] but it was SR 13 from 1907 to 1915, PSH 17 from 1937 to 1961, and unnumbered at other times.
