Originally known as "Summit Creek" (due to its location on that creek), Smithfield was founded in 1857 by brothers Robert and John Thornley and their cousin Seth Langton, who were sent north from Salt Lake City by LDS Church President Brigham Young to found a settlement on Summit Creek. After a preliminary scouting, Robert returned with his new wife Annie Brighton. The first winter was spent in a wagon box. By the next summer, with more settlers arriving, a small fort was built on the edge of the creek, one cabin of which remains. As the settlement grew, John Glover Smith was named as bishop to lead the church congregation, and the town took his name. In December 1902, the sizable Smithfield Tabernacle was completed. By 1917 the town had planted trees on both sides of its Main Street and had acquired a Carnegie library and a Rotary club. Dependent for many years on dairying, a Del Monte canning factory, and the sugar beet industry, the town is now essentially a bedroom community for Logan and its Utah State University.

According to the United States Census Bureau, the city has a total area of 5.0 square miles (12.9 km), all land.
