The Treaty Debates was a series of debates of the Second Dáil sitting in Dublin between the supporters and opponents of the Anglo-Irish Treaty signed on 6 December 1921 between representatives of the Irish Republic and the coalition government of Lloyd George. The Treaty had been negotiated by Irish envoys with plenipotentiary powers and required to be ratified by the Dáil and the British Houses of Parliament. The Treaty was approved on 7 January 1922 by a narrow margin of 64 to 57 (see Anglo-Irish Treaty Dáil vote).
