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.
F91 Dudelange were the defending league champions, their 16th title.
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.
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.
Almost all matches (95%+) from the 2022-23 season were streamed live on RTL.
