2022–23 Luxembourg National Division

The 2022–23 Luxembourg National Division season, also known as BGL Ligue, for sponsorship reasons, was the 109th of top-tier association football in Luxembourg. The season began on 7 August 2022 and will end on 21 May 2023. The league champion qualified to compete in the 2023–24 UEFA Champions League.

F91 Dudelange were the defending league champions, their 16th title.

The league is notable for being one of the few top-flight leagues to use the three substitute rule for the duration of the 2022-23 season, and it is the only top-flight men's European league to use the rule within the period.

Teams
Rodange 91 and RM Hamm Benfica were relegated at the end of the previous season, while Mondercange and UN Käerjéng 97 were promoted from the Luxembourg Division of Honour.

Relegation play-offs
Two play-off matches were played between two teams from the 2022–23 Luxembourg National Division and two teams from the 2022–23 Luxembourg Division of Honour to determine which teams would participate in the 2023–24 Luxembourg National Division.

Streaming
Almost all matches (95%+) from the 2022-23 season were streamed live on RTL.
