# Circonscription du Parlement d'Irlande du Nord

La Chambre des communes d’Irlande du Nord a existé de 1921 à 1973 en tant que Chambre basse de la législature dévolue de la partie du Royaume-Uni appelée Irlande du Nord.
Comme au Parlement britannique, les circonscriptions étaient classées comme circonscriptions de borough, de comté ou universitaire.
En 1921-1929, les 52 Membre du Parlement provinciaux ont été élus au scrutin proportionnel à vote unique transférable dans des circonscriptions plurinominales. Les circonscriptions qui ont élu un ou deux membres au Parlement du Royaume-Uni, entre 1922 et 1950, ont été utilisées pour les élections décentralisées en Irlande du Nord de 1921 à 1929.
Entre 1929 et 1969, il y avait 48 circonscriptions uninominales à un tour, selon le système uninominal majoritaire à un tour. La circonscription universitaire non territoriale a continué d'élire quatre membres au moyen du vote unique transférable.
Pour l’élection de 1969, 4 nouvelles circonscriptions territoriales ont été créées pour remplacer les circonscriptions universitaires. Les 52 circonscriptions ont cessé d’exister après la suspension du Parlement d'Irlande du Nord en 1972 et leur abolition en 1973.
