Luxembourg () is one of the 11 multi-member constituencies of the Chamber of Representatives, the lower house of the Belgian Federal Parliament, the national legislature of Belgium. The constituency was established as Arlon-Marche-Bastogne-Neufchâteau-Virton () in 1995 following the fourth Belgian state reform. It was renamed Luxembourg in 2003 following the re-organisation of constituencies across Belgium along provincial lines. It is conterminous with the province of Luxembourg. The constituency currently elects four of the 150 members of the Chamber of Representatives using the open party-list proportional representation electoral system. At the 2024 federal election the constituency had 220,550 registered electors.

Electoral system Luxembourg currently elects four of the 150 members of the Chamber of Representatives using the open party-list proportional representation electoral system. Seats are allocated using the D'Hondt method. Since 2003 only parties that reach the 5% threshold in the constituency compete for seats.

Electors may vote for the list (party) or for individual candidates, either main candidates or substitute candidates or a combination, on the list. They may vote for as many candidates as there are seats in the constituency. Split-ticket voting (panachage) is not permitted and will result in the ballot paper being invalidated. The minimum number of votes a candidate must obtain to get elected - the quotient - is calculated as the total votes received by the party divided by the number of seats in the constituency plus one. Half the ballot papers where there are no votes for main candidates (i.e. the elector has voted for the list or for substitute candidates only) are redistributed amongst main candidates in the order they appear on the ballot paper so that the candidate's total votes (personal votes plus redistributed votes) equals the quotient. The seats won by the party are then allocated to the candidates with the most number of total votes.
