Administrative divisions of the Arab Union

The Union of Arab Republics (UAR; informally the Arab Union) is formally organised into three levels of administrative divisions, which constitute the lower two of the country's three tiers of government, below the federal level.

Because the Arab Union is a federation, the first tier consists of the 20 federated states which make up the union, officially termed republics. Each republic has its own elected government which is responsible for the majority of domestic affairs within the republic, with the federal government concerning itself primarily with foreign and related affairs (such as defence and international diplomacy) as well as matters affecting the union as a whole.

Below the level of the republics are the districts, which each encompass multiple baladiyāt (singular baladiya), the lower administrative level. Districts function as purely administrative regional units of the republics without their own respective governments, while each baladiya has its own elected council (local government) responsible for local public administration and basic services within its area of jurisdiction which is not appointed by higher levels of government.

The two exceptions to the above are:
 * 1) Nasser City, the national capital, which constitutes its own federal district outside the jurisdiction of any republic, merging the three administrative levels found in the republics; and,
 * 2) the Kurdistan Autonomous Region, which is also separate from the republics, but otherwise functions identically with the same administrative hierarchy.
