Ferriday is a town in Concordia Parish in northeastern Louisiana, United States. The population, which is three-quarters African American, was 3,511 at the 2010 census.
Ferriday played a role in the promotion of blues music through the Haney's Big House lounge in the African-American community. Almost every Delta Blues musician played at Haney's. The Delta Music Museum in the downtown historic district is open daily to visitors, many of whom come from out of state. It is located next to the restored Arcade Theater. The museum contains exhibits on Ferriday natives, some of whom were blues, rock, pop, and country musicians.
The town claims to have produced more famous people per square mile than any other in America. This statement intrigued author Elaine Dundy, who explored both celebrities and townsfolk in her book, Ferriday, Louisiana, published by E. P. Dutton in 1991.
Ferriday is represented by churches of several major denominations, including a large Pentecostal congregation south of town on Louisiana Highway 15, as well as Baptist, Assembly of God, Presbyterian, Methodist, and Catholic.
Ferriday is situated on the west side of Lake Concordia and 8 miles (13 km) from Lake St. John, oxbow lakes noted for recreational and professional bass fishing.
