# Liste de sondages sur les élections générales britanniques de 2019

Cette page dresse la liste des sondages d'opinions relatifs aux élections générales britanniques de 2019 qui se sont tenues le 12 décembre 2019. Tous les sondages présents dans cet article sont issus d'instituts membres du British Polling Council.
Les sondages sont basés sur des échantillons représentatifs à l'échelle nationale qui incluent la Grande-Bretagne mais habituellement pas l'Irlande du Nord. Cela est généralement le cas de manière historique au Royaume-Uni pour ce qui est des sondages d'opinion, l'Irlande du Nord ayant un paysage politique différent du reste du pays, polarisé entre unionisme et le nationalisme.
