The Gare du Nord, officially Paris Nord, is one of the seven large mainline railway station termini in Paris, France. The station is served by trains that run between the capital and northern France via the Paris–Lille railway, as well as to international destinations in Belgium, Germany, the Netherlands and the United Kingdom. Located in the northern part of Paris near the Gare de l'Est in the 10th arrondissement, the Gare du Nord offers connections with several urban transport lines, including Paris Métro, RER and buses. It is the busiest railway station in Europe by total passenger numbers, and the busiest outside Japan. In 2015, the Gare du Nord saw more than 700,000 passengers per day.

The Chemins de fer du Nord, often referred to simply as the Nord company, was a rail transport company founded in September 1845 in Paris. It was owned by, among others, de Rothschild Frères of France, N M Rothschild & Sons of London, Charles Laffitte and Edward Blount, and Baron Jean–Henri Hottinguer. Baron James de Rothschild served as the company's president from its inception until his death in 1868.
