Seán Farrell (died 1 August 1972) was an Irish politician and teacher. He was first elected to Dáil Éireann as a Sinn Féin Teachta Dála (TD) for the Leitrim–Sligo constituency at the 1923 general election.[1] 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.[2]
