Jean Lafitte National Historical Park and Preserve, National historical park in Louisiana, United States.

Jean Lafitte National Historical Park and Preserve consists of six separate sites and a headquarters in the French Quarter at 419 Decatur Street, New Orleans. Three sites in Acadiana interpret Cajun culture: the Acadian Cultural Center in Lafayette, the Prairie Acadian Cultural Center in Eunice and the Wetlands Acadian Cultural Center in Thibodaux. The Barataria Preserve in Marrero covers 1,855 acres of bottomland hardwood forest, swamp and marsh, with trails and canoe tours; the Chalmette unit holds the 1815 battlefield and a national cemetery.

The site was established in 1978 to protect natural areas and historic places significant to Louisiana. It includes the Chalmette Battlefield, where in 1815 American troops under Andrew Jackson defeated British forces during the Battle of New Orleans.

The park honors the memory of French-speaking settlers who arrived in Louisiana during the 18th century and developed their own way of life. Their descendants still live in the region and maintain traditions such as French dialects, folk music, and distinct cooking methods, all of which visitors can experience at the cultural centers.

The six units lie far apart: the French Quarter visitor center at 419 Decatur Street, Barataria in Marrero, Chalmette about six miles southeast of New Orleans, and the Acadian centers in Lafayette, Eunice and Thibodaux. A car is needed between them. Barataria has trails and canoe tours; the Education Center runs curriculum-based programs for school groups.

In the Barataria section, elevated wooden boardwalks wind through wetlands where alligators, snakes, and over 200 bird species can be observed in their natural surroundings. The paths cross standing water and pass through dense vegetation, so animals often appear right beside visitors.
