The Seaboard Air Line Railroad (reporting mark SAL), which styled itself "The Route of Courteous Service," was an American railroad whose corporate existence extended from April 14, 1900 until July 1, 1967, when it merged with the Atlantic Coast Line Railroad, its longtime rival, to form the Seaboard Coast Line Railroad. The company was headquartered in Norfolk, Virginia, until 1958, when its main offices were relocated to Richmond, Virginia. The Seaboard Air Line Railway Building in Norfolk's historic Freemason District still stands and has been converted to luxury apartments.

At the end of 1925 SAL operated 3,929 miles of road, not including its flock of subsidiaries; at the end of 1960 it reported 4,135 miles. The main line ran from Richmond via Raleigh, North Carolina, Columbia, South Carolina, and Savannah, Georgia to Jacksonville, Florida, a major interchange point for passenger trains bringing travelers to the Sunshine State. From Jacksonville, Seaboard rails continued to Tampa, St. Petersburg, West Palm Beach and Miami.

Other important Seaboard routes included a line from Jacksonville via Tallahassee to a connection with the L&N at Chattahoochee, Florida, for through service to New Orleans; a line to Atlanta, Georgia, and Birmingham, Alabama, connecting with the main line at Hamlet, North Carolina; and a line from the main at Norlina, North Carolina, to Portsmouth, Virginia, the earliest route of what became the Seaboard.
