The city now known as Foristell started in 1856 under the name of "Millville". The first homes, as well as a railroad, were constructed in that year. In 1858, Millville built its first post office.

The community saw rapid growth during the Civil War. A mill and a tobacco factory were both established. It was during this time that a man by the name of Pierre Foristell gained respect throughout the community. The town of Millville officially changed its name to Foristell in 1875.

In 1979, Foristell was incorporated into a village. Just nine years later, however, the residents voted to make it a fourth-class city. This transition came about the following year, in 1989.

Foristell is home to Indian Camp Creek Park and Towne Park, which are operated by St. Charles County.
