Sheldon got its start with the Sioux City & St. Paul Railroad: railroad surveyors first surveyed and platted the town in 1871, and the Original Town Plat of Sheldon was filed for record on January 3, 1873.

The city was named for Israel Sheldon, a railroad promoter and shareholder of the Sioux City & St. Paul Railroad Company who lived in New York City.

After an incorporation vote failed in 1875, Sheldon voters approved incorporation on March 25, 1876, and the town elected its first officers that May.

Sheldon had just 30 residents in 1873 and 730 people in its first decennial census in 1880, but it has grown steadily ever since.
