Lithuania A Lyga

The first football league was established in Lithuania in 1924, and in various forms existed until 1939. Due to the Polish–Lithuanian War, clubs from Vilnius did not take part in early period of the Lithuanian football competitions.

Later during the period of Soviet occupation, a Lithuanian amateur top division existed, while professional players played in USSR football competitions. The Lithuanian professional top division was restored in 1990. The naming convention changed several times, but since 1999 the league is consistently referred to as A lyga.

The league system and size have also stabilized since 1999. League size varied mostly between 8 and 10 teams, with the exceptions of 2011 A Lyga featuring 12 teams, and 2020 A Lyga record low of only 6 teams. The teams play 4 rounds in regular season. The bottom placed team is relegated, while the 9th placed team contests a play-off with the 2nd placed team from the I lyga. The final list of participants often did not correlate to the final results of the previous season, as the participation were rather finalized through the Lithuanian Football Federation league licensing process.

The season usually kicks off in February or March and ends in November. Because of the harsh climate, there are no games in winter until early spring (April/March) and it depends on the weather and temperature. Games are played in indoor arenas on artificial grass. The winter transfer window opens in early January and lasts until mid March, while the summer transfer window lasts for most of July.

Lithuania sought to participate in the UEFA club competitions immediately after regaining the independence. However, due to political reasons, in 1991 Lithuania was banned by UEFA from continental competitions and Žalgiris was refused licensing to compete as a Lithuanian club rather than a Soviet club. Eventually, Lithuania became affiliated with UEFA in 1992. The A Lyga champion secures the right to play in UEFA Champions League qualification. The runner up and the 3rd-place team secure right to play in UEFA Europa Conference League qualification.

The best Lithuanian club result in UEFA competitions was achieved in 2022-23 UEFA club competition season by FK Žalgiris. The Lithuanian champions reached the group stage in the 2022–23 UEFA Europa Conference League. After the 2022-23 UEFA season, FK Žalgiris was the best performing A lyga club in Europe, taking #130 in UEFA Club Coefficients table.
