Wyoming Highway 230 (WYO 230) is a 78.74-mile-long (126.72 km) state highway in the U.S. State of Wyoming. It is known locally as Rivers Road and travels from WYO 130 approximately 8 miles (13 km) south of Saratoga south from there to intersect WYO 70 in Riverside and then heads southeast to the Colorado-Wyoming State Line. The Route continues southeast in Colorado as Colorado State Highway 125, then it turns northeast as Colorado State Highway 127. At the Wyoming-Colorado State Line, WYO 230 resumes. WYO 230 then heads northeast towards Laramie to end at Business Loop I-80/US 30/US 287 in Laramie. WYO 230 provides a scenic and less-traveled alternative for travelers who want to avoid Interstate 80 and US 30 but cannot take WYO 130 which is closed in the winter.

Wyoming Highway 230 basically crosses the same type of terrain as Wyoming Highway 130. The part of Highway 230 from WYO 130, south of Saratoga and the Wyoming-Colorado State Line slowly climbs out of the Platte Valley to a height of over 8,000 feet (2,400 m). At 10 miles (16 km) there is a junction with Wyoming Highway 70 in the community of Riverside where route 70 heads west to Baggs and 230 turns southeast towards the state line. At the state line WYO 230 ends briefly and the roadway continues southeast into Colorado as SH 125. 9 miles (14 km) into Colorado there is a junction with SH 127 north of Cowdrey, Colorado. SH 127 heads northeast approximately 9 miles (14 km) back into Wyoming where that state highway ends and WYO 230 resumes. From there Wyoming 230 climbs again into the southeastern edge of the Snowy Range Mountains through mostly forested areas. At 51.8 miles (Wyoming State Highway miles) there is a junction with Wyoming Highway 10 in Woods Landing. Further east along the Highway 230, it the route descends into the Laramie Basin. Highway 230 meets WYO 130 just west of Laramie, and the two routes run together into Laramie as Snowy Range Road. (This is the only instance in Wyoming where two state routes are merged). There is an interchange with Interstate 80 (Exit 311) at 77.7 miles (125.0 km), and route 230 ends at 78.74 miles (126.72 km) at I-80 BUS/US 30/US 287 (3rd Street).

Mileposts for the western segment run west-to-east; for the eastern segment, mileposts run east-to-west.
