The Étoile du Nord was an international express train.

It linked Paris Nord in Paris, France, with Brussels, Belgium, and, for most of its existence, also with Amsterdam CS in Amsterdam, the Netherlands.

In 1927, it became a luxury train between Paris Nord and Amsterdam CS, via Brussels, and was operated by its original operators, along with the Nederlandse Spoorwegen (NS) and the Compagnie Internationale des Wagons-Lits (CIWL).

Two years later, in 1939, the Étoile du Nord was suspended upon the outbreak of World War II.

In June 1984, it was downgraded to a two-class InterCity,[2] but three years later, it was reclassified as one of the inaugural EuroCity trains.
