The Old Mobile Site is a historic area in Le Moyne, Mobile County, Alabama. Its significance is related to the fact that it was once the location for the French settlement of La Mobile founded in 1702 and inhabited until 1712. The site was established as the French’s counter measure against the British forces that were already getting a stronger grip all over the country.

The Old Mobile Site is said to be something that could be seen as the French colonial counterpart of Jamestown, Virginia. It initially served the French Louisiana and initially led by Pierre Le Moyne d’Iberville. When he died, the settlement was governed by Jean-Baptiste Le Moyne de Bienville, d’Iberville’s younger brother.

The Old Mobile Site was added to the National Register of Historic Places in 1976. It is also eligible to become a National Historic Landmark, but no designation has been announced yet.
