Zaragoza lies in the north-east of the [[Iberian Peninsula]], in the rather arid depression formed by the valley of the [[Ebro]]. The Ebro cuts across the city in a west north-west by east south-east direction, entering the municipality at 205 [[Height above sea level|metres above sea level]] and exiting the municipality at a level of 180 metres above sea level.{{Sfn|Sotelo Pérez|Sotelo Navalpotro|2016|p=260}}

The city enjoys a beneficial location at the geographical centre of the rough hexagon formed by the Spanish cities of [[Bilbao]], [[Madrid]], [[Valencia]] and [[Barcelona]] and the French cities of [[Bordeaux]] and [[Toulouse]].{{sfn|Fernández Maldonado|Romein|2012|p=58}}

The municipality has a surface of {{cvt|973.78|km2}},<ref>{{Cite web |url=https://ssweb.seap.minhap.es/REL/frontend/inicio/municipios/2/13395/275 |access-date=12 August 2020 |publisher=Ministerio de Asuntos Económicos y Transformación Digital |title=Datos del Registro de Entidades Locales}}</ref> making it the ninth largest municipality in Spain.{{Sfn|Miguel González|2015|p=66}}

While the river banks are largely flat, the territory flanking them can display a rugged terrain, featuring {{Lang|es|muelas}} and escarpments.<ref name=medio /> The surrounding elevations rise up to heights of about 600–750 metres above sea level.{{Sfn|Sotelo Pérez|Sotelo Navalpotro|2016|p=260}} The locations near the meanders of the Ebro feature some sinkholes formed upon the subsidence of the [[gypsum]]-rich soil, that can form ponds fed from irrigation water.<ref name=medio /> There is also an instance of seasonal [[Endorheic basin|endorheic]] lagoon, {{Lang|es|la Sulfúrica}}, in the moors located in the southern part of the municipality.<ref name=medio>{{Cite web |url=https://www.zaragoza.es/contenidos/medioambiente/natural/Guia_LIFE_espanol.pdf |page=10; 12 |title=Zaragoza Natural.

The Roman core of Caesaraugusta was founded on the right bank of the Ebro, with the north-east corner limiting the confluence of the Ebro with the [[Huerva|Huerva river]], a modest right-bank tributary of the Ebro.{{Sfn|Adiego Adiego|2002|p=251; 253}} The Huerva runs through the city buried for much of its lower course.<ref>{{Cite web |url=https://www.elperiodicodearagon.com/noticias/aragon/huerva-cauce-mas-agraviado_556183.html |website=[[El Periódico de Aragón]] |title=El Huerva, el cauce más agraviado |date=31 January 2010 |first=Marga |last=Valiente}}</ref> Zaragoza is also located near the confluence of the Ebro with the [[Gállego (river)|Gállego]], a more voluminous left-bank tributary born in the [[Pyrenees]].{{Sfn|Adiego Adiego|2002|p=268}}
