The U.S. state of Utah operates a system of state routes that serve all portions of the state. The Utah Department of Transportation (UDOT) is responsible for maintaining all of the Interstate, U.S. Routes and state highways in the state. In official documents the state of Utah uses the term "state routes" for numbered, state maintained highways, since the legal definition of a "highway" includes any public road. UDOT signs state routes with a beehive symbol after the state's nickname of the beehive state. Most of the state routes are city streets and rural roads. However, there are a few state routes built to freeway or expressway standards, such as Bangerter Highway (SR-154) and State Route 201 in Salt Lake County, or the Legacy Parkway (SR-68) in Davis County and Southern Parkway (SR-7) in St. George. There are 3,658.04 miles (5,887.04 km) of state highways in Utah.

The numbers and routes of all Utah highways are assigned by the state legislature, currently documented in Utah Code Title 72, Chapter 4. Most signed state highways in Utah are currently numbered between 7 and 280. Generally, state highways in Utah are clustered together, such as State Routes 7, 8, and 9 all in close proximity to the St. George area, or State Routes 118, 119, and 120 in the Richfield area. There is no specific numbering based solely on direction, aside from numbers used for U.S. and Interstate routes. To wit, State Routes 68 and 257 both run north-south and State Routes 21 and 30 both run east-west.
