Cork North was a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas from 1923 to 1961.
The constituency elected 3 (and sometimes 4) 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 under the Electoral Act 1923, for the 1923 general election to Dáil Éireann, whose members formed the 4th Dáil.
The constituency returned 3 Teachtaí Dála initially.
It was abolished under the Electoral (Amendment) Act 1961, when it was replaced by the new constituency of Cork North-East and Cork Mid.
