Rivers in Spain: The Complete List

Spain’s landscapes are threaded with rivers that have shaped cities, farmlands and coastlines for centuries. From mountain-fed streams to wide lowland channels, these waterways matter for history, ecology and travel — and they offer a useful way to explore the country by region.

There are 86 Rivers in Spain, ranging from Adaja to Órbigo. For each entry you’ll find below data organized with Length (km),Basin / Mouth,Location,Notable (max 15 words), so you can compare size, drainage and key features at a glance.

Which rivers in Spain are the longest and where do they flow?

The longest include the Ebro, Tagus (Tajo), Duero, Guadiana and Guadalquivir — they flow from Spain’s interior toward the Mediterranean, Atlantic or border regions. Check the Length (km) and Basin / Mouth columns below to see exact distances and where each river empties, which helps identify major drainage patterns.

How can I use this list for trip planning or research?

Use the Location and Notable columns to find rivers near cities, parks or landmarks, then cross-reference Length (km) and Basin / Mouth to gauge accessibility and landscape type; for research, filter by basin or length and verify seasonal flow or protected-area status before visiting.
