, variant names are l'Isle de Petit Bois (French) and Petitbois Island.

Petit Bois originally extended about 7 miles east of the Alabama-Mississippi state line and was effectively located in both states. From 1933 to 1968, the eastern end of the island eroded (due to the effects of hurricanes and natural shoreline movement) until it was 1/2 mile west of the Mississippi state line. The island is approximately 6 miles (9.7 km) long and serves as a habitat for gulls, terns, plovers, alligators, and other wildlife.

Petit bois in French means "little woods". The island was so named by the early French explorers due to a small wooded section located on the eastern end of this mostly sand and scrub-covered island. Following the island's inundation during Hurricane Katrina, most of the trees comprising the little woods section have died.
