The Gamma Ethniki Katigoria (Greek: Γ΄ Εθνική Κατηγορία, lit. 'Third National Division') is the third-tier men's association football league in Greece.
The Gamma Ethniki began in 1965 as an amateur championship, while in 1983 it was changed to professional. Although not literally national (it is divided into North and South groups), Football League 2 is considered as a national division.
On 3 August 2010, it was announced that the division had been renamed Football League 2. From season 2013–14, the football League 2 was merged with the fourth division championship (Delta Ethniki) and renamed Gamma Ethniki once more. The new third division is held in six groups, with the clubs divided on the basis of geographical criteria, while it returns in an amateur form. From season 2014–15 until season 2016–17 the league was held in four groups, with the clubs divided basis of geographical criteria. The champion of each group was promoted to Super League 2.
From the 2017–18 season until the 2022–23 season, the league was held in eight groups, with the clubs divided by geographical criteria. The first team of each group qualified to a play-off tournament, consisting of two groups. The first two teams of each group were promoted to the Super League 2.
From 2023 onwards, the league is held in four groups with 18 clubs each. The top team of each group is promoted to the Super League 2 and bottom six teams are relegated to Local Championships.
For the 2025–26 season, the championship will be held with a total of 73 teams participating, divided in 5 groups with 12 teams each and 1 group with 13 teams. At the end of the season, 4 teams will be promoted to Super League 2 and 18 teams will be relegated to Local FCA Championships.
