St. Charles was laid out in 1854, and named for Saint Charles Borromeo (1538–1584), an Italian saint and cardinal. A post office has been in operation at St. Charles since 1855. St. Charles was incorporated in 1870.
The city was evacuated on April 17, 2009, when a large fire at North Star Foods, a poultry processing plant, threatened anhydrous ammonia tanks. Residents were allowed to return the next day.
Three properties in St. Charles are listed on the National Register of Historic Places: the 1874 Trinity Episcopal Church, the 1876 St. Charles City Bakery, and the 1890s Whitewater Avenue Commercial Historic District.
