James O'Connor (born 20 June 1997) is an Irish Fianna Fáil politician who has been a TD for the Cork East constituency since the 2020 general election, when he took the last seat in the constituency.
O'Connor comes from a farming background and was a member of Cork County Council from 2019 to 2020, representing the Midleton local electoral area.
He was the youngest member of the 33rd Dáil.
At the 2024 general election, O'Connor was re-elected to the Dáil, the first Cork East deputy to be returned in that election. He was subsequently appointed Cathaoirleach of the Committee on Enterprise, Tourism and Employment.
In October 2025, O'Connor criticized Taoiseach and Fianna Fáil party leader Micheál Martin, comparing him to the French "Sun King" Louis XIV. Martin said these comments were "hurtful" and "unacceptable."
