St. Tammany Parish administrative offices are located at 701 North Columbia Street, Covington LA 70433; phone: 985-809-8700.
The parish is named after a Native American given the moniker "saint" as a show of respect and admiration. Chief Tamanend was a chief in the Lenni-Lenape tribe, and had many dealings with white European settlers in the late 17th century and early 18th century. Due to his honesty and integrity, "Saint" Tamanend was honored with this name. He signed treaty documents which guaranteed equality for Native Americans in areas of the colonies, which was a very significant achievement. While many parishes in the state are named after either Native American tribes or European saints, St. Tammany has the distinction of being the only parish named after a Native American 'saint'.
