Knight Block, historic commercial building in Provo, Utah, United States

The Knight Block is a three-story rectangular building on South University Avenue in downtown Provo, Utah. It has a retail ground floor, a basement, and two upper floors of offices, built of red brick with gray limestone lintels. A clock tower rises above the roofline on the southwest corner, and three bays were added to the north end of the western face.

The Knight Block was constructed in 1900 as headquarters for Jesse Knight, a Provo businessman whose Humbug mine in the Tintic Mining District made him wealthy in the mid-1890s. Knight's investments, including mines, a bank, the Provo Woolen Mills and the Knight Investment Company, helped move Utah's economy from an agrarian base toward industry. The building was listed on the National Register of Historic Places in May 1977.

Jesse Knight named the building after himself; his Humbug mine in the Tintic District made him wealthy in the mid-1890s. His mining camps were promoted as the "cleanest mining camps in the west," and Knightsville grew as a saloon-free, privately owned camp inhabited mainly by Latter-day Saints. Knight left much of his fortune to Brigham Young University and other institutions.

The Knight Block stands on South University Avenue, which is also U.S. Route 189, in downtown Provo. The building has a basement and a ground floor of retail space, with offices on the two floors above. Its clock tower rises on the southwest corner, above the roofline, and can be picked out from the street.

The Knight Block was built for Jesse Knight, whose Humbug mine made him one of Provo's wealthiest men; his mining camps were called the "cleanest mining camps in the west." His fortune also paid for the Knight-Mangum House, the Knight-Allen House and the Jesse Knight House.
