The Edinburgh Agreement (full title: Agreement between the United Kingdom Government and the Scottish Government on a referendum on independence for Scotland) is the agreement between the Scottish Government and the United Kingdom Government, signed on 15 October 2012 at St Andrew's House, Edinburgh, on the terms for the Scottish independence referendum, 2014.

Both governments agreed that the referendum should:

The governments agreed to promote an Order in Council under Section 30 of the Scotland Act 1998 to allow a single-question referendum on Scottish independence to be held before the end of 2014 so to put beyond doubt that the Scottish Parliament can legislate for the referendum.

The agreement was signed by David Cameron, Prime Minister; Michael Moore, Secretary of State for Scotland; Alex Salmond, First Minister; and Nicola Sturgeon, Deputy First Minister.
