History
The town was first known as Hardin's Creek when it was settled by the Hardin family c. 1785. Catholic settlers from "Saint" Charles Co., Maryland, arrived in 1790. Their community was originally known as Saint Charles after their former home and new church.

The first Catholic settlers of the Hardin's Creek settlement were the brothers Edward Beaven and Charles Beaven from Maryland in 1786, followed by the brothers Mathew, Zachariah, Sylvester, and Jeremiah Cissell.

The community was the birthplace and hometown of George Elder, who – along with William Byrne – later returned from seminary in Maryland to found Saint Mary's College in 1821. The post office was established in 1858 as Saint Mary's for the school. The city was incorporated as St. Mary on May 26, 1865. The college closed its doors in 1976.

The city includes historical markers honoring the Sisters of Loretto and St. Mary's College.
