Petit Gulf was a location on the Mississippi River in North America. The gulf was an eddy or whirlpool that was smaller than the nearby Grand Gulf. The eddy lent its name to the nearby Petit Gulf Hills and Petit Gulf Creek. There was a settlement there prior to the 1828 organization of Rodney, Mississippi, and the Petit Gulf cotton cultivar, which was widely planted in the U.S. South before the American Civil War, was named for the landing and town.
