State Route 19 (SR-19) is a state highway in southeastern Utah, running 4.552 miles (7.326 km) in Emery and Grand Counties through Green River. It carries Business Loop I-70 along Main Street in Green River.

SR-19 begins at an interchange with I-70 west of Green River and then heads east through the center of town and turns south through the Utah Launch Complex of White Sands Missile Range. It ends at a frontage road just south of another intersection with I-70.

The main road through Green River was added to the state highway system in 1912 and numbered as part of US-50 in the 1920s. The state legislature defined the portion through Green River as State Route 19 in 1969, although the bypass on I-70 had not yet been built. Construction had begun in the mid-1980s, and when finished, the old route, along with a new connection to exit 164, became SR-19.

The entire route is in Green River.
