Penshurst station was opened by the South Eastern Railway on 26 May 1842.Penshurst Airfield, which was in operation from 1916–36, and again from 1940-46 as RAF Penshurst, was within ¼ mile (400 m) of the station.
In 1967 the station became unstaffed following which the original station buildings were demolished. In 1993 the line was electrified and services started to run through to London rather than being an extension of the Reading to TonbridgeNorth Downs Line service. Prior to electrification a new down platform was constructed opposite the up platform. New signalling was installed when the signal box was closed.
In 2007, a PERTIS (Permit to Travel) machine was installed at the street entrance to the Tonbridge-bound platform. The station was until December 2008 operated by Southeastern before it transferred to Southern, whose green signage was installed before October 2008.
