The Admiraal de Ruijter was an international train service linking Amsterdam with London.

The train was named after the Dutch Admiral Michiel de Ruyter, a remarkable choice because it was De Ruyter who attacked Britain and destroyed or seized many British navy ships during the Raid on the Medway several centuries earlier.

The Admiraal de Ruijter was one of the day services in the 1987 EuroCity network.

Each of these trains lost its EuroCity label after one year of service because it did not meet the EuroCity criteria for service quality;[2] sometimes other rolling stock was used and the on-board catering was minimal from the start.

British Rail used its class 86 and Mark 2 coaching stock on the Harwich - London part.
