Château-Landon is a station on line 7 of the Paris Métro in the 10th arrondissement.
The station was opened on 5 November 1910 as part of the first section of the line from Opéra to Porte de la Villette. It is named after the Rue Château-Landon, a street which was built on property once owned by a family from Château-Landon in Seine-et-Marne. The street is on the alignment of the Roman road from Lutetia towards the North via Saint-Denis.
It was planned to become the end of the future new line. It is also planned to build an underground pedestrian connection to the RER Line E station of Magenta, which would also link to the Gare du Nord and the Gare de l'Est.
