Most Aragonese rivers are tributaries of the [[Ebro]] River, which is the largest river in Spain and divides the community in two. Of the tributaries of the left bank of the river, the ones originating in the Pyrenees, the [[Aragón (river)|Aragón River]] stands out. Its headwaters are in Huesca, but it ends at the community of Navarre, the [[Gállego (river)|Gállego]] and the [[Cinca (Spain)|Cinca]], which joins the [[Segre (river)|Segre]] just before emptying into the Ebro at the height of [[Mequinenza]]. On the right bank, the [[Jalón (river)|Jalón]], [[Huerva]] and [[Guadalope]] stand out.

In the stream bed of the Ebro river, near the border with Catalonia, the [[Mequinenza Reservoir]], of {{val|1530|u=hm<sup>3</sup>|fmt=gaps}} and a length of about 110&nbsp;km; it is popularly known as the "Sea of Aragon".

The small Pyrenean mountain lakes called [[Ibón|ibon]]es merit special mention. These lakes are very scenic, originating during the last [[glaciation]], and are usually found above {{val|2000|u=m|fmt=gaps}}.

The Autonomous Community lies within three hydrographic regions, the Ebro River, the [[Tagus]] River (which originates in the [[Sierra de Albarracín]] range), and the [[Júcar]], which has as its main river in this community the [[Turia (river)|Turia]].
