Numidian was an ancient Saharan and North African language written in the Libyco-Berber alphabet.
Numidian was used by the ancient Numidians, who lived mainly in the region corresponding to modern Algeria and Tunisia. It is known from inscriptions, especially funerary and monumental texts, rather than from a surviving body of literature. The language is generally regarded as an early Berber language, though the surviving evidence is too limited to reconstruct every feature with certainty.
The Libyco-Berber script is an ancient writing system related to the broader history of Berber scripts. Some modern scholars connect it historically with Tifinagh, the alphabet used by Tuareg communities, but the exact development of the scripts over time is complex.
Numidian inscriptions are important because they preserve local language evidence from a period when Latin and Punic were also used in North Africa. They should not be confused with Punic, the Semitic language associated with Carthage.
