Heemstede-Aerdenhout is a railway station in Heemstede and Aerdenhout, Netherlands. The station opened on 1 October 1891 and is located on the site of the old Toll house for the Leidsevaart canal, which still flows next to the station from Haarlem to Leiden. This canal still follows the Oude Lijn (Amsterdam - Rotterdam) closely. The train soon became the favored method of travel after the station opened, and the canal has gone out of use since the end of the second world war. The current station building was opened in 1958 and was one of the first Dutch viaduct stations.
Formerly all trains running between Rotterdam and Amsterdam operated via Haarlem and stopped in Heemstede. Intercity trains still stop in Heemstede, though the fastest train line from Leiden to Amsterdam now runs via Schiphol railway station, not Haarlem.
