U.S. Route 195 (US 195) is a north–south United States Highway, of which all but 0.65 miles of its 94.02 miles (1.05 of 151.95 km) are within the state of Washington. The highway starts in rural Idaho north of the city of Lewiston as a state highway in an interchange with US 95. As the road crosses into Washington it becomes a state highway that connects communities in the Palouse region of Eastern Washington. US 195 travels north, serving the cities of Pullman, Colfax and Rosalia in Whitman County before continuing into Spokane County to its terminus in the city of Spokane at an interchange with Interstate 90 (I-90).

The first section of US 195 designated as part of Washington's state highway system was codified in 1913 from Colfax to Spokane as the Inland Empire Highway and from the Idaho state line to Pullman as the Second Division of the Eastern Route of the Inland Empire Highway. The two highways were included as part of State Road 3 in 1923 and US 195 during the creation of the US Highway System on November 11, 1926. Originally, the northern terminus of the highway was at US 95 in Sandpoint, but was truncated to Spokane after US 2 was extended west from Bonners Ferry in 1946.

US 195 was cosigned with Primary State Highway 3 (PSH 3) from US 95 to Spokane and PSH 6 from Spokane to Newport from the creation of the primary and secondary state highways in 1937 until the 1964 highway renumbering. US 195 was extended south into Idaho after the relocation of US 95, designated as the North and South Highway in 1916, onto its present freeway in 1975. Bypasses of Pullman, Rosalia, and Plaza were completed during the early 1970s, converting portions of US 195 into a divided highway.
