Segre is a river tributary to the Ebro (Ebre in Catalan) with a basin comprising territories across three states: France, Andorra and Spain (although culturally they all belong to the Catalan Countries).

The Segre has its sources on the north face of the Pic del Segre ("Segre's Peak") in the French comarca of Alta Cerdanya in (Northern Catalonia). It follows an east-west direction all along the Cerdanya Valley (entering Spain at Puigcerdà) until La Seu d'Urgell, where it meets the Valira River coming from Andorra. From this point it adopts a south-western course across the pre-Pyrenees (with several dams along its gorges) and the western plains of Catalonia. It passes through Balaguer, Lleida and joins into the Ebro at Mequinenza.

Among its tributaries: Valira (from Andorra), Noguera Pallaresa, Noguera Ribargorçana, Cinca.
