Sligo is a former parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas. Covering the most (but not all) of County Sligo, it existed from 1937 to 1948. It elected three Teachtaí Dála (TDs) to the Dáil, using the Single Transferable Vote method of proportional representation (PR-STV).
