The river is {{convert|657|km|abbr=on}} long and drains an area of about {{convert|58000|km2|abbr=on}}. It flows through Córdoba and Seville and reaches the sea at [[Sanlúcar de Barrameda]], flowing into the Gulf of Cádiz in the [[Atlantic Ocean]].

=== Course ===
The course of the Guadalquivir is divided into three parts. This division is based on the main course of the river and its confluence with other rivers.<ref name=Demarcación>{{citation |year=2015 |title=Anejo Nº2.

The Guadalquivir originates at an elevation of about 1,350 meters above sea level in a place known as Cañada de las Fuentes,<ref>{{Cite journal|url=http://sea-entomologia.org/Publicaciones/PDF/BOLN45/549_552BSEA45NBOdonatofaunaCazorla.pdf|first=José|last=Lara Ruiz|title=Odonatos del Parque Natural de Cazorla-Segura-las Villas (Jaén, SE de España) (Insecta: Odonata)|journal=Boletín Sociedad Entomológica Aragonesa|issue=45|year=2009|page=549}}</ref> in the [[Sierra de Cazorla]] mountain range. The upper course of the river runs from the source of the Guadalquivir roughly to [[Mengíbar]]. It includes its junction with the [[Guadalimar]], just east of Mengíbar.<ref name=Demarcación />

The middle course {{lang|es|curso medio}} starts near Mengíbar and ends near [[Palma del Río]]. It includes the river's confluence with the [[Guadiana Menor]] and the [[Genil]].<ref name=Demarcación /> The latter confluence is located between Palma del Río and [[Peñaflor, Spain|Peñaflor]].

The lower course of the Guadalquivir runs from Palma del Río to the sea.<ref>{{citation |last1=Costa |first1=S. |last2=Gutiérrez Mas |first2=J.M. |last3=Morales |first3=J.A. |year=2009 |journal=Revista de la Sociedad Geológica de España |title=Establecimiento del Régimen de Flujo en el Estuario del Guadalquivir, mediante... |publisher=Sociedad Geológica de España |url=https://sge.usal.es/archivos/REV/22(1-2)/art03.pdf |page=25 }}</ref> On its lower course, the Guadalquivir is joined by the river [[Corbonés]] and (from the north west) by the [[Rivera de Huelva]].<ref name=Demarcación /> The [[marsh]]y lowlands at the river's mouth are known as "[[Las Marismas]]". Here, the river borders the [[Doñana National Park]] reserve.
