Louis O'Hara

Early life and education The son of a solicitor, O'Hara is from Cashla, a townland in Athenry civil parish. O'Hara graduated with a Bachelor of Arts in Public and Social Policy and a Master of Arts in Public Activism and Advocacy, both from the University of Galway.

Although O'Hara is the great-grandnephew of Thomas O'Donnell, a nationalist MP for Kerry who was the first person to speak Irish in the British House of Commons, he has described his family as not overtly political and more from "the Fine Gael tradition" than his Sinn Féin background.

Political career O'Hara joined Sinn Féin at the age of 17, stating he was drawn in by the party's focus on representing young people. At the 2020 general election, aged 22 and still a student at University of Galway, O'Hara lost out to Anne Rabbitte of Fianna Fáil.

In 2020 O'Hara criticised Sinn Féin's Northern Ireland Finance Minister Conor Murphy after Murphy stated that Paul Quinn, who was murdered in 2007, was involved in smuggling and criminality.

At the 2024 general election, O'Hara was elected Teachta Dála for the Galway East constituency, having won 14% of the first preference vote. In a party selection convention held shortly after the general election, Martin McNamara was selected to replace O'Hara on Galway County Council as a Sinn Féin councillor representing the Athenry-Oranmore local electoral area.

Political views O'Hara describes himself as a republican and left-wing politician whose politics are centred on Irish unity, social justice, and economic equality. He has said he joined Sinn Féin because of its positions on republicanism, reunification, and social policy.

On constitutional issues, O'Hara strongly supports Irish unification and argues that political authority over Northern Ireland should not remain within the British state. He believes the Irish Government should actively prepare for a future border poll through mechanisms such as a Citizens' Assembly, an Oireachtas committee, and formal planning documents outlining how a united Ireland would function institutionally and economically.

Economically, O'Hara advocates greater state investment in housing and infrastructure. He argues that the Irish housing crisis of the 2020s stems from inadequate public housing delivery and insufficient investment in infrastructure. He supports expanded affordable and public housing construction, as well as infrastructure improvements to facilitate private development. On cost-of-living issues, he criticises the Fine Gael/Fianna Fáil government of the 2020s as disconnected from the financial pressures facing households. He opposed the removal of temporary cost-of-living supports such as energy credits and argued that disabled people were disproportionately negatively affected by recent budgetary changes.

In transport policy, O'Hara supports expanding public transport infrastructure, particularly rail. He has campaigned for the reopening and expansion of the Western Rail Corridor and supports upgrades to Galway rail infrastructure, including double-tracking lines into Galway City. He also supports major road infrastructure projects, such as the Galway outer ring road to address congestion.

On the European Union, O'Hara supports continued EU membership but argues that the EU has acquired excessive influence over Irish decision-making in some areas. He cites EU migration policy and the Mercosur trade agreement as examples where he believes Irish national interests were overridden by EU-level decision-making.
