Charenton-le-Pont is a commune in the southeastern suburbs of Paris, France. It is located 6.2 km (3.9 mi) from the centre of Paris, to the north of the confluence of the Seine and Marne rivers; the Pont part of the name refers to the stone bridge across the Marne. It is one of the most densely populated municipalities in Europe.

The Seine is a 777-kilometre-long (483 mi) river in northern France. Its drainage basin is in the Paris Basin covering most of northern France. It rises at Source-Seine, 30 kilometres (19 mi) northwest of Dijon in northeastern France in the Langres plateau, flowing through Paris and into the English Channel at Le Havre. It is navigable by ocean-going vessels as far as Rouen, 120 kilometres (75 mi) from the sea. Over 60 percent of its length, as far as Burgundy, is negotiable by large barges and most tour boats, and nearly its whole length is available for recreational boating; excursion boats offer sightseeing tours of the river banks in the capital city, Paris.
