Seaford is a station on the Babylon Branch of the Long Island Rail Road. It is officially located at New York State Route 27 and Jackson Avenue in Seaford, New York, however parking areas stretch as beyond Washington Avenue east of this corner, and west towards the interchange with New York State Route 135. Westbound trains typically terminate at Penn Station or Grand Central, and eastbound trains terminate at Babylon.

Seaford station is typical of the elevated Babylon Branch stations that were rebuilt during the mid-to-late 20th century. What makes it atypical, however, is its close proximity to the Seaford-Oyster Bay Expressway interchange. The station was opened as a ground-level station on May 26, 1899. It was raised on April 15, 1966 as part of the grade elimination project, which was constructed and completed in 1966–67.

Beginning in 2008 the station underwent another renovation, with complete rebuilding of the station's platforms and shelters, plus the installation of an elevator. Though the reconstruction was scheduled to be completed on January 1, 2010, it was finished by July 31, 2009, several months ahead of schedule.

The station has one 12-car-long high-level island platform between the two tracks.
