Numidia (202 BC – 46 BC) was an ancient Berber kingdom in present-day Algeria and part of Tunisia (North Africa) that later alternated between being a Roman province and being a Roman client state, and is no longer in existence today. It was located on the eastern border of modern Algeria, bordered by the Roman province of Mauretania (modern day Algeria) to the west, the Roman province of Africa (modern day Tunisia) to the east, the Mediterranean Sea to the north, and the Sahara Desert to the south. Its people were the Numidians.
