March 1925 Dáil by-elections

The March 1925 Dáil by-elections were held in seven Dáil constituencies to fill nine vacancies in the 4th Dáil. They occurred following the resignation from the Dáil of members of the National Group, who had each been elected at the 1923 general election as TDs for Cumann na nGaedheal. It has been described as a "mini-general election". It is the only occasion at a Dáil by-election in which more than one seat was filled within the same constituency; this occurred in Dublin North and Leitrim–Sligo.
