Colnbrook railway station was a station on the now closed railway line between West Drayton and Staines West, on the western edge of London, England.

It opened in 1884 to serve the village of Colnbrook, perhaps anticipating that one day it would grow into a larger settlement.

[1] It was located on the original route of the Great Bath Road, and under the present flight path near the end of one of Heathrow Airport's main runways.

Goods services were withdrawn the following year, but part of the line still remains in use for aggregates traffic and for deliveries to a fuel terminal serving the nearby Heathrow Airport.

[2] Part of the route may be reused for the proposed Heathrow Airtrack link between Staines and Heathrow Airport.
