The three districts of Luxembourg (French: districts, German: Distrikte, Luxembourgish: Distrikter) are the top-level administrative divisions of the Grand Duchy of Luxembourg. The districts are further subdivided into cantons:
The cantons were created on 24 February 1843. In 1857, Mersch District was created from the cantons of Mersch and Redange. However, this fourth district was abolished in 1867, when the re-arrangements of ten years previously were undone.
