State Highway 50 (SH-50) is a 8.092-mile (13.023 km) state highway in Twin Falls and Jerome counties in Idaho, United States, that connects with U.S. Route 30 (US 30), north of Kimberly, with Idaho State Highway 25 (SH-25), west of Eden. It crosses over the Snake River and connects with Interstate 84 (I-84) along its route.

Nearly all of SH-50 is located within rural agricultural area. While it is passes near a few cities, it does not enter any communities. Despite its status as a connector route, that provides eastern access to the city of Twin Falls from I-84, SH-50 is not part of the National Highway System (NHS), a network of roadways important to the country's economy, defense, and mobility.

SH-50 begins at an intersection with US 30 and North 3500 East in Twin Falls County, north of the city of Kimberly and about one mile (1.6 km) north of the city's downtown area. {US 30 heads west along East 3800 North toward Twin Falls, Filer, and Boise and heads south along North 3800 East toward Kimberly, Hansen, and Burley. North 3800 East heads north toward the Twin Falls waterfall on the Snake River.)

From its western terminus, initially as a five-lane road, but quickly narrowing to a two-lane road, SH-50 heads east along East 3800 North for about 2.2 miles (3.5 km), parallel with and about one mile (1.6 km) north of US 30. From there (a point northwest of Hansen) SH-50 curves to head northeast and reaches the Snake River after approximately 1.6 miles (2.6 km). SH-50 crosses the river and the Snake River Canyon on the Hansen Bridge. (The Snake River forms the border between Twin Falls and Jerome counties.)

After crossing the Hansen Bridge and entering Jerome County, SH-50 continues for roughly 1.7 miles (2.7 km) as it curves to head north and reaches its diamond interchange with I-84. As it approaches I-84, SH-50 widens to four-lanes. (There is a truck stop on the southwest side of the interchange along a frontage road, as well as some commercial establishments on the southwest and northeast sides of the interchange.)

After crossing the freeway on an overpass, SH-50 quickly narrows back to two-lanes as it continues north along South 1150 East for about 0.8 miles (1.3 km) before curving sharply to head east along East 900 South. (South 1150 East continues due north though its intersection with East 900 South.) After approximately 1.2 miles (1.9 km), SH-50 curves sharply again to head north along South 1300 East. (East 900 South continues due east though its intersection with South 1300 East.) SH-50 heads north for about one mile (1.6 km) before it connects with Idaho State Highway 50 Connector (SH-50 Conn.). From that junction SH-50 Conn. continues north along South 1300 East to end at SH-25 (westbound), while SH-50 curves sharply to the east again and immediately reaches its eastern terminus at SH-25 (eastbound), at a point roughly three miles (4.8 km) west of Eden. (From the western terminus of SH-50, eastbound SH-25 heads east along East 800 South toward Eden and Hazelton, while westbound SH-25 curves sharply to immedicaly connect with the north end of SH-50 Conn. and then heads north along South 1300 East toward Jarome.)
