努米底亚（前202年－前46年）是一个古罗马时期的柏柏尔人王国，如今这一国家已经消亡。其领土大约相当于现今的阿尔及利亚东北以及突尼斯的一部分（皆位于北非）。当时以出产精锐骑兵闻名。迦太基名将汉尼拔就是以努米底亚骑兵打下早期多场战争的胜利，后来也因努米底亚骑兵投向罗马而战败。其后，努米底亚先后成为了罗马帝国的行省之一和附庸国。努米底亚王国具体的位置是在现今的阿尔及利亚东部边境地区。其领土西端与罗马帝国的另一行省毛里塔尼亚接壤（即现今的阿尔及利亚），东端则与罗马帝国的阿非利加行省（迦太基故地，即现今的突尼斯）接壤，其领土北临地中海，南接撒哈拉沙漠。其民族构成为努米底亚人。

Numidia (202 BC – 46 BC) was an ancient kingdom of the Numidians in what is now Algeria and a smaller part of Tunisia, in North Africa. Numidia was originally divided between Massylii in the east and Masaesyli in the west. During the Second Punic War (218-201 BC), Massinissa, king of the Massylii, defeated Syphax of the Masaesyli to unify Numidia into one kingdom. The kingdom began as a sovereign state and later alternated between being a Roman province and a Roman client state. It was bordered by the kingdoms of Mauretania (modern-day Morocco) 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. It is considered to be the first major state in the history of Algeria and the Berber world.
