League of the Institutes (Arabic: دوري المؤسسات العراقي) was the highest national league in Iraq before the creation of the Iraqi Premier League. At first, it consisted of only Baghdad-based teams, but teams from all of Iraq were allowed in 1973. It began its first season in 1948, but after its first edition, it was not held for a further seven years until it restarted in 1956 and from there it continued up until 1974. During its existence, the League of the Institutes was dominated by Al-Shorta, Al-Quwa Al-Jawiya and Amanat Baghdad who together won 15 of the 18 championships.
