Fort Pike State Historic Site is a decommissioned 19th-century United States fort, named after Brigadier General Zebulon Pike. It was built following the War of 1812 to guard the Rigolets pass in Louisiana, a strait from the Gulf of Mexico, via Lake Borgne, to Lake Pontchartrain bordering New Orleans. It was located near the community of Petite Coquille, now within the city limits of New Orleans.
