U.S. Route 89 (US 89) in the U.S. state of Utah is a north–south United States Highway spanning more than through the central part of the state, making it the longest road in Utah. Between Provo and Brigham City, US-89 serves as a local road, paralleling (and occasionally concurring with) Interstate 15, but the portions from Arizona north to Provo and Brigham City northeast to Wyoming serve separate corridors. The former provides access to several national parks and Arizona, and the latter connects I-15 with Logan, the state's only Metropolitan Statistical Area not on the Interstate. When US-89 was established in the state in 1926, the road initially extended north to US-91 in Spanish Fork.

While some state agencies have developed their own sets of standards, including their own MUTCDs, these must substantially conform to the federal MUTCD.
