The Garonne (Latin: Garumna, Occitan: Garona) is a river in southwest France.

The 650 km long river rises in the Val d'Aran (Spanish Pyrenees), flowing via Toulouse towards Bordeaux, where it flows into the Gironde, a sea arm of the Bay of Biscay. In its flow, it is joined by two other major rivers, the Lot and the Dordogne to become the Gironde and join the Atlantic Ocean.
