State Route 260 (SR 260) is a 37.98-mile-long (61.12 km) state highway serving Franklin and Adams counties in the U.S. state of Washington. The highway begins at SR 17 west of Connell, and travels through the Washtucna Coulee to Kahlotus, forming the southern terminus of SR 21 and the northern terminus of SR 263, before a concurrency with SR 261 to SR 26 in Washtucna.
SR 260 had previously existed as a gravel road between Connell and Kahlotus in 1916 and was designated as Secondary State Highway 11A (SSH 11A) from Yakima to Connell and Secondary State Highway 11B (SSH 11B) from Connell to Washtucna in 1937. SSH 11A in the Connell area became an extension of SSH 11B in 1957, which in turn became SR 260 in the 1964 highway renumbering.
