The Bogue Falaya, also known as the Bogue Falaya River, is a 28-mile-long (45 km) river in southeastern Louisiana in the United States. It is a tributary of the Tchefuncte River, which flows to Lake Pontchartrain. The river flows through an area of mixed pine-hardwood and bottomland hardwood forests on the Gulf Coastal Plain. The name is derived from the Choctaw words bogu, “river,” and falaya, "long." A portion of the Bogue Falaya in St. Tammany Parish has been designated a "Natural and Scenic River" by the state government of Louisiana.
