Conor Byrne (died 19 April 1948) was an Irish politician and medical practitioner. He was first elected to Dáil Éireann as a Sinn Féin Teachta Dála (TD) for the Longford–Westmeath constituency at the 1923 general election. He did not take his seat in the Dáil due to Sinn Féin's abstentionist policy. He lost his seat at the June 1927 general election. He stood as a Clann na Poblachta candidate at the 1948 general election but was not elected.
