Waterford is a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas. The constituency elects four deputies (Teachtaí Dála, commonly known as TDs) on the system of proportional representation by means of the single transferable vote (PR-STV).

The Constituency Review Report 2023 of the Electoral Commission recommended that no change be made at the next general election.
