The Garamantes (probably from Berber language: igherman; meaning: cities) are a Saharan people who use an elaborate underground irrigation system, and establish a prosperous Berber kingdom in the Fezzan area of modern-day Libya, in the Sahara desert.

They are a local power in the Sahara between 500 BCE and 700 CE.There is little textual information about the Garamantes.

Even the name Garamantes is a Greek name which the Romans later adopted.

Most of what we know comes from Greek and Roman sources, and recent archaeological excavations in the area, though large areas in ruins are still unexcavated.

Another important source of information are the abundant rock art, many of which depict life prior to the rise of the realm.
