Arkansas Highway 197 (AR 197, Ark. 197, and Hwy. 197) is the designation for a state highway in the U.S. state of Arkansas. The route is split into three sections, all of which are located in western Arkansas. The first and longest section begins at AR 22 in Subiaco, and ends near Lake Dardanelle southwest of Tokalon. The second section begins at AR 22 in New Blaine, and ends just south of Shoal Bay. The third section begins at AR 10 in Booneville, and ends about 0.3 miles (0.48 km) south. All three signed highways are located within Logan County.

The first and longest section begins at AR 22 in Subiaco. The route heads towards the north, before taking a sharp turn towards the east near Wilkins, right at the intersection of AR 393. The route heads more in a northeasterly direction for about 6.5 miles (10.5 km) before entering the town of Scranton, and intersecting AR 109. The route continues east for about 7 miles (11 km) before reaching its northern terminus near Lake Dardanelle. The route is about 17.33 miles (27.89 km) long.

The second section begins at AR 22 in New Blaine. The southern section of AR 197 around New Blaine is a former alignment of AR 22, and is still used as a primary road to access the town center. AR 197 breaks off of the former AR 22 alignment just east of the town center, heading north. The route ends at Shoal Bay Recreation Area about 1.0 mile (1.6 km) north of New Blaine. The route does not intersect any other signed highways or communities.

A third section of AR 197 can be found in Booneville. This section begins at AR 10, just west of AR 116, and ends about 0.3 miles (0.48 km) south of its northern terminus, providing access to the Rockline Industries Booneville plant.

The entire route is in Logan County.
