Dáil constituencies in County Dublin (historic)

This category includes constituencies in Dublin created for the United Kingdom House of Commons used by Irish republicans to elect the First Dáil and those created for the Northern Ireland House of Commons and the House of Commons of Southern Ireland used to elect the Second Dáil. Although only Sinn Féin members took their seats as TDs in the first two Dála, MPs from other parties could have done so if they wished so all constituencies used in 1918 and 1921 are entitled to a Dáil Éireann constituency article.
