State Route 163 (SR 163), also referred to as the Laughlin Highway, is a state highway in southern Clark County, Nevada. The route connects the town of Laughlin to the rest of the state via U.S. 95.
NV 163 and Arizona State Route 95 provide the next closest public Colorado River crossing to Hoover Dam. Due to the restriction of commercial vehicles over the dam following the September 11 attacks, SR 163 comprised part of the required detour for truck traffic traveling between the Las Vegas and Phoenix metropolitan areas from September 11, 2001, to October 19, 2010, when the Mike O'Callaghan–Pat Tillman Memorial Bridge just downstream from the dam was opened to traffic.
Prior to the renumbering of Nevada state routes on July 1, 1976, SR 163 previously comprised the northern part of State Route 76 and all of State Route 77.
