Ratu Ovini Bokini Ratu (3 November 1944 – 15 January 2009) was a Fijian chief and political leader. Bokini, who held the chiefly title of Tui Tavua, succeeded Ratu Epeli Ganilau as Chairman of the Great Council of Chiefs on 21 July 2004, and was re-elected to this post for a full three-year term on 27 July 2005.
A formal gathering of mostly traditional chiefs chosen by the country's 14 provincial councils, along with some appointees of the national government and the Council of Rotuma, the Great Council of Chiefs functioned as an electoral college to select Fiji's President, along with 14 of the 32 members of the Senate. Informally, the Council advised the Fijian government on every aspect of political life. Although not mandated by the Constitution, the chairman's role was therefore a very influential one.
During late April 2007, all members of G.C.C were suspended by the Interim Prime Minister, Frank Bainimarama. The suspension included the chairman, Ovini Bokini and all other members of G.C.C after the President's nomination for the Vice-President position was rejected by some G.C.C members.
