The District of Luxembourg was one of three districts of the Grand Duchy of Luxembourg. It contained four cantons, divided into 44 communes:
It bordered the district of Grevenmacher to the east, the district of Diekirch to the north, the Belgian province of Luxembourg (Wallonia) to the west and the French Département of Moselle (Grand Est) to the south. It also had the highest per capita income of the districts of the duchy. Its per capita income was $72,300.
After the reorganization of Luxembourg's administrative divisions in 2015, all three districts were abolished per 3 October 2015.
