The 2021–22 Iraqi Third Division League was the 48th season of what is now called the Iraqi Second Division League, the fourth tier of the Iraqi football league system, since its establishment in 1974. The number of clubs in the league have varied throughout history for various reasons; 173 clubs participated in this year's edition. The top 38 teams in the league are promoted directly to Iraqi Second Division League. There is no general date for the start of the league, but each subsidiary football association chooses the best time to start the league in their region.[1]
A total of 173 teams are competing for the league after some teams withdrew for financial reasons. The teams are originally promoted to the Iraqi Second Division League based on the rule of one qualified team out of every five participating teams. The number of teams that will be promoted to the Second Division League will be 38 teams.[2]
The 173 clubs are supposed to be divided into 18 groups by location (some of these groups play in subgroups as well), and each group represents the province to which these clubs belong and lies within its borders. But there are 5 provinces that do not have clubs that play in this level.
