Ferriday is a town in Concordia Parish in northeastern Louisiana, United States. The population, which is three-fourths African American, was 3,511 at the 2010 census.

Ferriday claims to have produced more famous people per square mile than any other American small town. This statement intrigued author Elaine Dundy who probed that phenomenon while profiling both celebrities and townsfolk in her book, Ferriday, Louisiana, published by E. P. Dutton in 1991.
