Dublin County was a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas from 1921 to 1969. The method of election was the single transferable vote form of proportional representation (PR-STV).

The constituency was created in 1921 as a 6-seater, 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.

Under the Electoral Act 1923, it became an 8-seat constituency for the 1923 general election to the 4th Dáil. It remained at that size until major boundaries changes for the 1937 election to the 9th Dáil, when its geographical area was reduced and its representation cut to 5 seats.

Further boundary changes for the 1948 general election to the 13th Dáil saw its area further reduced, and representation cut to 3 seats. It was expanded to a 5-seater again for the 1961 general election to the 17th Dáil, before its abolition for the 1969 general election. It was replaced by Dublin County North and Dublin County South.
