The Cinca (Spanish: [ˈθiŋka]; Catalan: [ˈsiŋkə], locally: [ˈsiŋka]; Aragonese: A Cinca, IPA: [a ˈθiŋka]) is a river in Aragon, Spain. Its source is in the Circo de Pineta, in the Ordesa y Monte Perdido National Park, in the Aragonese Pyrenees. It is a tributary to the Segre River, with its confluence at La Granja d'Escarp, not far from the point where the Segre flows into the Ebro River. The Cinca River flows through a rich agricultural region.

The Cinca is born in the area of Pineta and begins its descent between cascades and torrents, in the mountains of the Tres Sorores. It flows across the entire Pineta valley. In Bielsa it joins with the Barrosa, and somewhat later the Cinqueta. Upon reaching Aínsa it is joined on the right side by the Ara River, where the Mediano Reservoir is located. Immediately after the Mediano, after crossing the throat of the Entremón, it is again dammed at the El Grado Reservoir near El Grado. Just after this, it is joined on the left side by the Ésera River, the Cinca's most important tributary.

On the right side it is joined by the Vero River, and in Monzón by the Sosa River on the left. Later, the Alcanadre pours into it on the right. Finally, in Massalcoreig, it joins the Segre to flow into the Ebro River.
