The Golden Square (Arabic: المربع الذهبي, al-Murabbaʿ al-dhahabī), also known as the Four Colonels (Arabic: العقداء الأربعة, al-ʿiqdā' al-arbaʿa), was a cabal of pro-Fascist and pro Nazi army officers of the Iraqi armed forces who played a part in Iraqi politics throughout the 1930s and early 1940s.

In time, these men represented real power as successive Iraqi governments sought the support of the military for survival.

The members of the Golden Square looked to Nazi Germany to support them and, for his part, Grobba enthusiastically encouraged them to do so.

[6] On 1 April 1941, Rashid Ali and the Golden Square launched a coup d'etat to topple the government of the regent, Prince 'Abd al-Ilah.

The subsequent Anglo-Iraqi War ended disastrously for Rashid Ali and the members of the Golden Square who, for the most part, fled Iraq as the British closed in on Baghdad.
