Fort Proctor is a ruined 19th century fort in St. Bernard Parish, Louisiana, USA. Also known as Fort Beauregard or Beauregard's Castle (after P.G.T. Beauregard, who supervised its construction with the architect J.G. Totten) it is located on the shore of Lake Borgne just north of the mouth of Bayou Yscloskey. At the time it was built in the 1850s, there was also a railroad port called "Proctorville" adjacent.
