NEWLY released data shows the majority of people in the north and south of Ireland would vote in favour of the island's reunification.
The European Movement Ireland EU Poll 2026 asked people across the country how they would vote if a referendum on Irish unity were held tomorrow.
Some 59 per cent of respondents in Ireland and 63 per cent of respondents in Northern Ireland said that they would vote in favour of it.
Those who said they would vote against it totalled 29 per cent in the North, and 22 per cent in the south.
A further 19 per cent of people polled in the south said they ‘don’t know’ how they would vote, while eight per cent of people in the North said the same.
The results of the poll, which was undertaken by Amárach Research, were published this week.
They also show that 73 per cent of those polled in Northern Ireland said they would vote to rejoin the EU if a referendum to reverse Brexit was held by the UK tomorrow, with 23 per cent voting against.
European Movement Ireland CEO David Geary said: “Ten years on from Brexit, there is clear and growing pro-European outlook in the North, shaped in part by the legacy of the UK EU Referendum, alongside a strong showing of support for a united Ireland within the EU.”
He added: “Ireland is also set for its first EU Presidency without the UK, given this, it is vital that the North’s voice is reflected in the Presidency and in wider shared island initiatives.
"Our research, tracking NI–EU relations and EU sentiment in Northern Ireland over the past four years, points to important discussions ahead about the island’s future.”
Sinn Féin Senator Conor Murphy said the Irish government should now make preparations for referendums on Irish unity.
“Respondents to this poll, both in the north and south, have overwhelmingly indicated support for a united Ireland within the EU,” he said.
“We know that in the event of Irish reunification the entire island would automatically achieve EU membership status, the European Council adopted guidelines to this effect in 2017.
“Sinn Féin has long demanded real action towards constitutional change from the Taoiseach and Irish government.
He added: “This poll again demonstrates that the citizens of Ireland are far ahead of the government on this issue. People across the island can see how the British government is failing citizens in the north and why this must change.
“Irish unity is the direction most citizens across the island wish to move towards.”
Mr Murphy confirmed that his party plans to “bring forward legislation before the summer requiring the Irish government to begin planning and preparations”.
"It is time for the Taoiseach to listen, and begin preparing for the significant constitutional change we will face as a country in an orderly, peaceful and successful way,” he added.
