Madauros (Madaurus, Madaura) was a Roman-Berber city and a former diocese of the Catholic Church in the old state of Numidia, in present-day Algeria.

A colony of veterans was established there; it was called Colonia Flavia Augusta Veteranorum Madaurensium under emperor Nerva.

[2] The city was fully Romanised in the fourth century, with a population of Christian Berbers who spoke mainly African Romance, according to Theodor Mommsen.

The ruins of Madauros are close to the actual city of M'Daourouch (Arabic: مداوروش) in present-day Algeria.

It is possible to see: Apuleius, the author of the famous novel The Golden Ass, which is the only Latin novel to survive in its entirety,[4] was born in Madauros in the 120s.
