Cork Mid, North, South, South East and West was a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas from 1921 to 1923. The constituency elected 8 deputies (Teachtaí Dála, commonly known as TDs) to the Dáil, on the system of proportional representation by means of the single transferable vote (PR-STV).

The constituency was created in 1921 as an 8-seat constituency, under the Government of Ireland Act 1920, for the 1921 general election to the House of Commons of Southern Ireland, whose members formed the 2nd Dáil. It succeeded the constituencies of Cork Mid, Cork North, Cork South, Cork South East and Cork West which were used to elect the Members of the 1st Dáil and earlier UK House of Commons members.

The constituency covered most of County Cork except for Cork city and the northern eastern and eastern parts of the county.

It was abolished under the Electoral Act 1923, when it was replaced by the new Cork North and Cork West constituencies,^[1] which were first used in the 1923 general election for the 4th Dáil.

The constituency's most notable TD was Michael Collins, who was Minister for Finance in the First Dáil of 1919, Director of Intelligence for the IRA, and member of the Irish delegation during the Anglo-Irish Treaty negotiations. He was killed during the Civil War in an ambush on 22 August 1922 near the village of Béal na Bláth.
