State Route 168 is a state highway in the state of Utah that spans 1.160 miles (1.867 km) from Riverdale, Utah to Hill Air Force Base in Weber County.

This route is essentially a short access road to the former north gate at Hill Air Force Base. The southern terminus of this route is at the now-closed north gate of Hill Air Force Base. From there it travels downhill and northeast before turning north and ending at SR-60 (Riverdale Road).

The road from Hill Air Force Base's north entrance to SR-60 was added to the state highway system in 1962 by the state legislature and has remained essentially unchanged since.

The entire route is in Weber County.
