U.S. Route 197 marker

U.S. Route 197 (US 197) is a north–south United States Highway, of which all but 2.76 miles of its 69.93 miles (4.44 of 112.54 km) are within the state of Oregon. The highway starts in rural Wasco County in Central Oregon at an intersection with US 97. US 197 travels north as a continuation of The Dalles-California Highway No. 4 through the cities of Maupin, Tygh Valley, and Dufur to The Dalles. Within The Dalles, the highway becomes concurrent with US 30 and intersects Interstate 84 (I-84) before it crosses over the Columbia River on The Dalles Bridge into Washington. The highway continues through the neighboring city of Dallesport in Klickitat County and terminates at a junction with State Route 14 (SR 14).

US 197 was established in 1952 using the existing The Dalles-California Highway, itself created as a part of the initial named Oregon highways in 1917. US 197 traveled from its current northern terminus at Dallesport to US 97 in Maryhill along Primary State Highway 8 (PSH 8) and US 830, successors to the original State Road 8 designated along the corridor in 1907. The Dallesport–Maryhill section was transferred to SR 14 in 1979, but was not recognized by the American Association of State Highway and Transportation Officials (AASHTO) until 2006.
