The Bièvre (French pronunciation: [bjɛvʁ]) is a 34.6-kilometre (21.5 mi) long river of the Île-de-France région that flows into the Seine (left bank) in Paris.

[1] The name is often thought to derive from the archaic French word bièvre meaning "beaver".

[3] From there, it flows through the following départements and towns: The river enters Paris near Stade Charléty (close to the border between the 13th and 14th arrondissements), and reaches the Seine River in the Latin Quarter (5th arrondissement) close to Île de la Cité.

Tanneries, butcher shops and dye-makers were built along its banks, leading to serious pollution concerns.

Eleven kilometers are canalised under slabs and 5 km have disappeared under rubble and urbanisation in Paris.
