Records of members of the Oireachtas

This is a list of records relating to the Oireachtas, the national parliament of Ireland, which consists of the President of Ireland, and two Houses, Dáil Éireann, a house of representatives whose members are known as Teachtaí Dála or TDs, and Seanad Éireann, a senate whose members are known as senators.

The First Dáil consisted of the Sinn Féin MPs who were elected in the United Kingdom general election of 14 December 1918. They refused to attend the British House of Commons and instead assembled for the first time on 21 January 1919 in the Mansion House in Dublin as the revolutionary unicameral Dáil Éireann.

1,292 TDs have served in the Dáil between 1919 and 2018. The title Father of the Dáil is usually and unofficially conferred on the longest-serving member.

Longest-serving former TDs

This is a list of former TDs who have served at least 30 years in the Dáil. Unless otherwise specified, start and end dates given are those of the relevant general election. Unless stated, the TD listed did not stand in the end-date election.
