The Floridian was a train operated by Amtrak from 1971 to 1979 that ran between Chicago and Florida, with two branches south of Jacksonville terminating at Miami and St. Petersburg. For its Nashville to Montgomery segment, its route followed that of several former Louisville & Nashville Railroad (L&N) passenger trains, including the Pan-American and the Humming Bird. Originating in Chicago, the train served Lafayette and Bloomington, Indiana; Louisville and Bowling Green, Kentucky; Nashville, Tennessee; Decatur, Birmingham, Montgomery and Dothan, Alabama; and Thomasville, Valdosta and Waycross, Georgia.

The Louisville and Nashville Railroad, commonly called the L&N, was a Class I railroad that operated freight and passenger services in the southeast United States.
