The following is the standings of the 3rd Division''s 2009/10 football season. This is the 4th rated football competition in Iran after the Azadegan League, Persian Gulf Cup and 2nd Division. Iranian football''s 3rd division is the fourth-highest football division overall in the Iranian football league system. Before 2001, the 3rd division was known as the 4th division, but this was changed when Iran''s football structure officially became professional. The league consists of six groups, with the total number of teams in each group is twelve. The groups are organized in a manner such that teams closer to each other geographically end up in the same group. Because of this the 3rd division can be considered as a regional league.
