State Route 131 (SR-131) is a 3.047-mile (4.904 km) state highway in Bluffdale, Utah, United States, routed entirely on Porter Rockwell Boulevard. The open section is a 2.5 miles (4.0 km) spur southwest from 14600 South (SR-140), but when completed it will extend west to Redwood Road (SR-68).

As of August 2022, the west end of the route is at Redwood Road (SR-68). SR-131 proceeds northeast on Porter Rockwell Boulevard as a five-lane section of the highway. It crosses a bridge over the Utah and Salt Lake Canal, Jordan River, tracks for the Union Pacific Railroad and FrontRunner commuter rail, and Jordan and Salt Lake City Canal. At Harmon Day road it continues northeast as a two-lane road with a center turn lane. It passes through newer developments in Bluffdale, as well as Summit Academy High School. The route straightens out to the north to continue on to its eastern terminus at an intersection with 14600 South (SR-140), just south of the Utah State Prison.

The route was created by an action of the Utah Transportation Commission on September 16, 2016, which officially designated SR-131 along Porter Rockwell Boulevard from SR-68 to SR-140. In exchange, the section of SR-140 west of 800 West was cancelled.

The entire route is in Bluffdale, Salt Lake County.
