Guadahortuna is a municipality of the province of Granada, in the autonomous community of Andalusia, Spain.

During Moorish Al-Andalus the municipality got its name, which means "River of fortune".

During this period of time, it served as a border zone where Christian troops would enter Moorish territory in order to harass its inhabitants.

In 1492, Guadahortuna became part of the city of Granada until 1557, when the municipality bought its independence with money from all its inhabitants.

It passes through Montejícar, Guadahortuna, Alamedilla, Alicún de Ortega, Dehesas de Guadix and eventually it flows into Guadiana Menor river.
