Harper Ward is an unincorporated community in Box Elder County, Utah, United States.

It is located along Utah State Route 38 for 8 miles (13 km) between Brigham City and Honeyville.

In 1852, John Gibbs and George Foster moved from Brigham City and began to homestead the land, creating the first permanent settlements in the area.

In 1855, following a visit from President Brigham Young, Anson Call constructed a fort in the area, which would give the community its name for the next fifty years.

John Gibbs became the first branch leader (1853–1856, 1858–1860), and was succeeded by Joseph Tomlinson (1856–1858), Chester Loveland (1860–1865), James May (1865–1866), and Thomas Harper (1866–1877).
