The Fijian coup d'état of December 2006 was a coup d'état in Fiji carried out by Commodore Frank Bainimarama against Prime Minister Laisenia Qarase and President Josefa Iloilo. It was the culmination of a political crisis that had begun the previous year when when the Qarase government introduced three bills to the Fijian Parliament. The Qoliqoli, Land Tribunal, and Reconciliation, Tolerance, and Unity Bills dealt with the ongoing ethnic conflicts in Fiji and the aftermath of the 2000 coup, and were considered to be pro-ethnic Fijian. Bainimarama, the Commander of the Republic of Fiji Military Forces (RFMF), presented the government with a list of demands on October 16 that included withdrawing the bills. Attempts at negotiation failed and the military launched a coup on 4 December. Parliament was dissolved, Qarase and his cabinet were dismissed, and some civilian officials were placed under house arrest. After the Great Council of Chiefs refused to appoint a cabinet friendly to the military, Bainimarama reached an understanding with Iloilo and reinstated him as President on 4 January 2007. Iloilo then appointed Bainimarama acting Prime Minister in charge of the Interim Cabinet.

The Great Council of Chiefs is a Fijian constitutional body. It previously existed from 1876 to March 2012 and was re-established in May 2023.
