Inter-Régions Division

Inter Régions Division (also known as Ligue Inter Régions de football) is the third-highest division overall in the Algerian football league system. The division has six groups based on the region of the country, which are East, West and Centre-East, Centre-West, South-east and South-west each containing 16 teams from their respective regions. Each year the first from each group are promoted to Ligue 2 and the last three clubs from each group are relegated to the Ligue Régional I.

History
Over the seasons, the Algerian third division championship has had several names. At the beginning of the 1960s, and following the various hierarchical restructurings of Algerian football, this level ended up being organized into three groups in accordance with the geography of the country (east, center and west) and which contained subgroups during a few seasons, it was the period of the division of honor which lasted from 1966 to 1988.

The Algerian D3 was restructured into six regional groups (west, center, east 1, east 2, south-east and south-west) to become the regional championship which lasted until 1999. In this year, Algerian football officials tried to adopt a new structure by creating the Super-division for D1 and a single national division for D2 as well and the National 2 for D3 with five groups (west, center, east, south-east and south-west). This format was quickly abandoned the following season and the D3 returned to the old organization (Regional 1) and underwent temporary changes until the creation of the Inter-region championship in 2004. This Inter-region division takes over the three-way organization groups (east, central and west).

Between 2010 and 2020, a new competition formula was adopted under the name of the National Amateur Division, better known as National, after the establishment of professionalism for divisions one and two. From the 2020-2021 season, the third division championship once again changes its status, format and name. It is made up of six groups, and managed from this season by the Inter-regional Football League which also manages the Algerian D4.
