Greenfields railway station is a railway station on the Gawler railway line which is located adjacent to Parafield Airport, in the northern Adelaide suburbs of Parafield and Parafield Gardens. It is located 15.5km by railway from the Adelaide Railway Station. The station was opened in 1969 and was originally referred to as 'Green Fields' in passenger timetables. Greenfields is one of only two stations on the Gawler line to have a pedestrian underpass (the other is Parafield Gardens). The other stations have had theirs closed due to concerns with safety and vandalism.

Passenger services to Greenfields will be cut back from April 2008 due to changes to the Gawler Central line timetable. Passengers are encouraged to use the nearby Mawson Lakes Interchange, which was completed in 2006.
