The Super League 2 (), also officially known as A2 Ethniki Katigoria (), is the second-tier professional men's association football league in Greece. Made up of 20 teams in two groups, it is usually played from September to May. Super League 2 is ranked below the Greek Super League 1 and above the Greek Third National Division in the Greek football league system. All of the Super League 2 clubs take part in the Greek Football Cup, the annual Greek Cup competition.
The league was founded in 2019, after the restructuring of the Greek football league championships, replacing the Football League (former Beta Ethniki) as the second level in the league pyramid.
Twelve (12) clubs participated in the league's first season and second season of operation.
For the third season (2021âÂÂ2022) the league was restructured after the abolition of the third level Football League. Starting with this season, the team became known as Betsson Super League 2 as the online betting operator entered into a title sponsorship agreement. The league included 24 teams including Olympiacos, PAOK, Panathinaikos and AEK Athens also participating. Levadiakos was promoted to Super League and did not participate; A.E. Kifisia F.C. was an addition relegated from Super League.
