Dublin Mid was a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas from 1921 to 1923. The constituency elected 4 deputies (Teachtaí Dála, commonly known as TDs) to the Dáil, using proportional representation by means of the single transferable vote (PR-STV).
The constituency was created in 1921 out of portions of the UK Parliament constituencies of Dublin College Green and Dublin Harbour. It was a four-seat constituency, under the Government of Ireland Act 1920, for the 1921 election to the House of Commons of Southern Ireland, whose members formed the 2nd Dáil. It was abolished under the Electoral Act 1923.
The constituency consisted of the College Green and the Dublin Harbour divisions of Dublin city.
