Parafield opened in 1928 to serve the then-under construction Parafield Airport, located adjacent to the line.

In 1982, the station was rebuilt at the same time as standardisation of the mainline from Adelaide to Port Pirie. In April 2008, the eastern platform was rebuilt, followed by the western platform in 2014. The project included the construction of a new park-and-ride facility on the eastern side of the station. To the west of the station lies the Australian Rail Track Corporation standard gauge line to Crystal Brook.

Parafield has two side platforms and is serviced by Adelaide Metro Gawler line services. It is a designated high-frequency station, with trains scheduled every 15 minutes on weekdays, between 7:30am and 6:30pm.
