Constituencies ({{langx|lb|Walbezierk}}; {{langx|fr|Circonscription électorale}}; {{langx|de|Wahlkreis}}) are used to elect representatives ('deputies') to Luxembourg's unicameral national legislature, the Chamber of Deputies.

Electoral law in Luxembourg is dictated by Articles 51, 52, and 53 of the Constitution.{{in lang|fr}} [http://www.legilux.public.lu/leg/textescoordonnes/recueils/constitution_droits_de_lhomme/CONST1.pdf Constitution et droits de l'homme] {{webarchive|url=https://web.archive.org/web/20080216021501/http://www.legilux.public.lu/leg/textescoordonnes/recueils/constitution_droits_de_lhomme/CONST1.pdf |date=2008-02-16 }}. 25 November 2004. Service central de legislation. URL accessed 9 May 2006. The number of deputies is set at sixty,Constitution, Article 51(3). and boundaries of the constituencies are based on administrative cantonal boundaries.Constitution, Article 51(6). As a result, the constituencies have greatly differing populations, so each elects a different number of deputies, dependent upon the share of the national population.Council of State, 15 July 1993.

Suffrage is universal and compulsory amongst adult resident citizens not otherwise disqualified.Constitution, Articles 52(1), 52(2). Luxembourg's electoral system is a form of the Hagenbach-Bischoff system (a variant of the D'Hondt method), which allocates seats to party lists by proportion of the votes won in each constituency. Under Luxembourg's system, each citizen may vote for as many candidates as there are deputies elected from that constituency. As a result, the national popular vote has no significance, as it reflects only the number of votes cast, and not the number of voters or the number of deputies elected.
