The area was settled by 120 Norwegian immigrants from Lisbon, Illinois on June 7, 1855; including Osmond and Anna Sheldahl and five of their children. It incorporated as a city on January 18, 1882.
The Chicago and Northwestern Railway established a NE to S rail line through Sheldahl during the 1880s. The Chicago, Milwaukee, St. Paul, and Pacific Railroad connected with this line 2 miles north in Slater. In 2005, Union Pacific Railroad sold a 25-mile discontinued rail corridor—which included the recently abandoned line through Sheldahl—to the Iowa Natural Heritage Foundation, which enabled the construction of the recreational High Trestle Trail. Access to the trail, including a parking area and washroom, is located in Sheldahl.
