State Route 161 (SR-161) is a 3.084-mile (4.963 km) long state highway, designated as a rural major connector, completely within Millard County in central Utah. The highway connects Interstate 70 (I-70) to I-15 while providing service to historic Cove Fort. The route was once part of U.S. Route 91 (US-91), but was renumbered to SR-161 in the 1970s, in parallel with the construction of I-70.
Located entirely in southeastern Millard County, SR-161 starts at a diamond interchange with the westernmost exit on I-70 before it terminates at I-15. The road continues northward until it reaches the historic Cove Fort and the associated visitors center. On the eastern side of the highway is a Utah Department of Transportation (UDOT) maintenance center. SR-161 starts to make a gentle turn to the northeast, passing a filling station, which also serves as a rest area as part of a public–private partnership between UDOT and the owners of the station. The highway intersects I-15 and comes to an end at a cattle guard on Black Rock Road northwest of the interchange with I-15.
