Harahan is a city in the U.S. state of Louisiana and suburb of New Orleans. The city of Harahan is located in Jefferson Parish; its population was 9,116 at the 2020 census.
Harahan was named in honor of James Theodore Harahan, president of the Illinois Central Railroad from 1906 to 1911. The Illinois Central track runs parallel to Airline Highway.

In 1914, the Harahan Land Company, composed of ICRR officials, bought the Southern University tract of land and subdivided it. Residents included
