Fionntán Ó Súilleabháin (born 1968/1969)[1] is an Irish Sinn Féin politician who has been a Teachta Dála (TD) for the Wicklow–Wexford constituency since the 2024 general election.

[3] In June 2023 Ó Súilleabháin faced backlash from colleagues for his outspoken criticism of Ireland’s immigration policy.

At a Wexford County Council meeting, Ó Súilleabháin raised concerns about the planned emergency migrant centre at Slaney Manor in Barntown, which was set to house up to 213 people.

He highlighted local frustration with the lack of consultation or information about the project, suggesting this gap had led to misinformation and fear.

Despite the criticism, Ó Súilleabháin maintained that fear of being labelled "far-right" or "racist" prevented a frank debate on immigration.
