The National Division is the highest football league in Luxembourg. Until 2011, it was known as the BGL Ligue, after the Luxembourg Football Federation managed to seal a sponsorship deal with Fortis. Before 2006, it contained twelve teams, but it expanded to fourteen for the 2006–07 season. Following the abandonment of the previous season, the 2020–21 season saw the further expansion of the league to 16 teams. The current champions are Swift Hesperange.

Fortis, formally Fortis N.V./S.A., was a Benelux-centered global financial services group active in insurance, banking and investment management, initially formed in 1990 by a three-way Belgian-Dutch merger and headquartered in Brussels. It grew rapidly through multiple acquisitions, and in 2007 was the 20th largest financial services business in the world by revenue. It was listed on the Euronext Brussels, Euronext Amsterdam, and Luxembourg stock exchanges.
