The Guadiana Menor River is a river in southern Spain, one of the main tributaries of the Guadalquivir River, on its left bank. It has a total length of 182 km (including the length of its upper stretches known as the Baza River and Gallego River), and it drains a large basin of 7,251 km². Administratively, it flows through the provinces of Granada and Jaén in the autonomous community of Andalusia.

In 1977, the Guadalquivir Hydrographic Confederation published a book titled Guadalquivires, which endorsed the thesis that the true source of the Guadalquivir is the Guadiana Menor–Barbata, considered as a single river.
