Amendments to the Constitution of Ireland are only possible by way of referendum. A proposal to amend the Constitution of Ireland must be initiated as a bill in Dáil Éireann, be passed by both Houses of the Oireachtas (parliament), then submitted to a referendum, and finally signed into law by the president of Ireland. Since the constitution entered into force on 29 December 1937, there have been 32 amendments to the constitution.
An ordinary referendum in Ireland is a referendum on a bill other than a bill to amend the Constitution. The Constitution prescribes the process in Articles 27 and 47. Whereas a constitutional referendum is mandatory for a constitutional amendment bill, an ordinary referendum occurs only if the bill "contains a proposal of such national importance that the will of the people thereon ought to be ascertained". This is decided at the discretion of the President, after a petition by Oireachtas members including a majority of Senators. No such petition has ever been presented, and thus no ordinary referendum has ever been held.
In Ireland, direct elections by universal suffrage are used for the President, the ceremonial head of state; for Dáil Éireann, the house of representatives of the Oireachtas or parliament; for the European Parliament; and for local government. All elections use proportional representation by means of the single transferable vote (PR-STV) in constituencies returning three or more members, except that the presidential election and by-elections use the single-winner analogue of STV, elsewhere called instant-runoff voting or the alternative vote. Members of Seanad Éireann, the second house of the Oireachtas, are partly nominated, partly indirectly elected, and partly elected by graduates of particular universities.
This is a list of referendums related to the European Union, or referendums related to the European Communities, which were predecessors of the European Union. Since 1972, a total of 48 referendums have been held by EU member states, candidate states, and their territories, with several additional referendums held in countries outside the EU. The referendums have been held most commonly on the subject of whether to become a member of European Union as part of the accession process, although the EU does not require any candidate country to hold a referendum to approve membership or as part of treaty ratification. Other EU-related referendums have been held on the adoption of the euro and on participation in other EU-related policies.
The Twenty-fourth Amendment of the Constitution Bill 2001 was a proposed amendment to the Constitution of Ireland to allow the state to ratify the Treaty of Nice of the European Union.

The referendum was held on the same day as referendums on the prohibition of the death penalty and on the ratification of the Rome Statute of the International Criminal Court, both of which were approved.
The Constituency Commission is an independent commission in Ireland which had advised on redrawing of constituency boundaries of Dáil constituencies for the election of members to Dáil Éireann and European Parliament constituencies prior to the establishment of the Electoral Commission in 2023. Each commission was established by the Minister for Housing, Planning and Local Government after the census. The Commission then submitted a non-binding report to the Oireachtas, and was dissolved. A separate but similar Local Electoral Area Boundary Committee fulfilled the same function for local electoral area boundaries of local government areas.

Dáil Éireann is the lower house, and principal chamber, of the Oireachtas, which also includes the president of Ireland and a senate called Seanad Éireann. It consists of 160 members, each known as a Teachta Dála. TDs represent 39 constituencies and are directly elected for terms not exceeding five years, on the system of proportional representation by means of the single transferable vote (PR-STV). Its powers are similar to those of lower houses under many other bicameral parliamentary systems and it is by far the dominant branch of the Oireachtas. Subject to the limits imposed by the Constitution of Ireland, it has power to pass any law it wishes, and to nominate and remove the Taoiseach. Since 1922, it has met in Leinster House in Dublin.
The Thirty-eighth Amendment of the Constitution of Ireland is an amendment to the Constitution of Ireland which altered the provisions regulating divorce.

The amendment was effected by an act of the Oireachtas, the Thirty-eighth Amendment of the Constitution Act 2019.
Various proposals have been considered since the 1980s to extend the franchise in Irish presidential elections to citizens resident outside the state. In 2019, the then government introduced a bill to amend the constitution to facilitate this extension. The bill lapsed in January 2020 when the 32nd Dáil was dissolved for the 2020 general election, but was restored to the order paper in July 2020.
