The Arab Socialist Ba'ath Party – Iraq Region (Arabic: حزب البعث العربي الاشتراكي في العراق Hizb Al-Baath Al-'Arabi Al-Ishtiraki fi Al-'Iraq), officially the Iraqi Regional Branch (Iraq being a "region" of the Arab nation in Ba'ath ideology) of the Arab Ba'athist political party founded in 1951 by Fuad al-Rikabi. It was part of the original Ba'ath Party (1951–1966), changing its allegiance to the Iraqi-dominated Ba'ath movement following the 1966 split within the Ba'ath Party.
