The Annan Plan, also known as the Cyprus reunification plan, was a United Nations proposal to resolve the Cyprus dispute. The different parts of the proposal were based on the argumentation put forward by each party in meetings held under the auspices of the UN. The proposal was to restructure the Republic of Cyprus to become the "United Republic of Cyprus", a federation of two states. It was revised a number of times before it was put to the people of Cyprus in a 2004 referendum, and was supported by 65% of Turkish Cypriots, but only 24% of Greek Cypriots.
