Buchtar Tabuni (born 1979) is a Papuan independence activist, leader of the National Committee for West Papua (Komite Nasional Papua Barat, KNPB).
Indonesia's control over the province of Papua has been disputed since 1963, when the country took control of the province from the Dutch. A separatist movement formed, battling the Indonesian government for more than four decades. During this time, one sixth of the province's population died in military operations. Papuans also cite economic issues, stating that the area's natural resources are exploited exclusively for the benefit of the national capital, Jakarta.
Buchtar studied engineering in Makassar, South Sulawesi. In 2008, he organized the International Parliamentarians for West Papua (IPWP), an organization devoted to repealing the Act of Free Choice, the 1969 referendum that had given Indonesia sovereignty over West Papua.
He was arrested on 3 December 2008, in his house in Sentani near Jayapura, for organizing a 16 October protest supporting the launch of IPWP in the UK Parliament. The following day, fifty protesters gathered outside the Jayapura police station to call for his release.
Prosecutors sought a ten-year sentence against him on three charges: an act of treason (Article 106), provocation (Article 160), and acts against the state (Article 212). Buchtar's attorneys described the case as an attempt to stifle free speech in Papua, asking, "If outside Papua, people can freely raise their opinions, why is free speech still restrained in Papua, and treated as treason?"Amnesty International considered him to be a prisoner of conscience, "imprisoned solely for peacefully expressing [his] views".Human Rights Watch also lobbied for his release along with that of other non-violent Papuan political prisoners.
