St. Mary's County, Maryland

Saint Mary's County (often abbreviated as St. Mary's County) is a county located in the U.S. state of Maryland.

As of 2000, the population was 86,211, and more recent population estimates are closer to 100,000. Its county seat is Leonardtown. The name is in honor of Mary, the mother of Jesus.

The county is part of the Southern Maryland region.


The settlement of Lord Baltimore's Maryland began with the arrival of passengers from England at St. Clement's Island in the Potomac River in what is now southwestern St. Mary's County on March 25, 1634 (the anniversary of this landing being annually celebrated as Maryland Day). The passengers arrived in two vessels, the Ark and the Dove, which had set sail from the Isle of Wight on November 22, 1633. The county is also home to the first Catholic Mass celebrated in the original thirteen colonies.

St. Mary's County was the first county established in Maryland, in 1637, probably by an order of the Governor.

The county seat and state capital was St. Mary's City.

St. Mary's County is where Francis Scott Key, the author of a poem which became The Star Spangled Banner, and professional wrestler Scott Hall grew up. St. Mary's County was the birthplace of Dashiell Hammett, and Orlando "Tubby" Smith, head basketball coach at the University of Minnesota. The largest employer is Patuxent River Naval Air Station and its related aerospace contract firms. There are both Amish and Mennonite communities who follow traditional ways. Tobacco, once dominant crop, has declined in recent years. Maryland International Raceway (Budd's Creek) attracts many auto racing enthusiasts.
