State Route 14 (SR 14) is a 180.66-mile-long (290.74 km) state highway in the U.S. state of Washington. The highway travels east-west on the north side of the Columbia River, opposite Interstate 84 (I-84) to the south in Oregon. SR 14 forms a section of the Lewis and Clark Trail Scenic Byway and begins at an interchange with I-5 in Vancouver. The highway travels east as a four-lane freeway through Camas and Washougal and intersects I-205. SR 14 continues east as a two-lane highway through Clark, Skamania, Klickitat, and Benton counties before it ends at an interchange with I-82 and U.S. Route 395 (US 395) near Plymouth.

SR 14 was established in 1968 as the successor to US 830, created in 1926 with the original United States Numbered Highways, and Primary State Highway 8 (PSH 8). PSH 8 was added to the state highway system in 1905 as a short road along the Columbia River between Washougal and Lyle and was extended westwards to Vancouver and eastwards to Maryhill by 1913. PSH 8, designated as the Evergreen Highway, was extended east to the Tri-Cities in 1949 and this section was retained during the 1964 state highway renumbering and the decommissioning of US 830.
