Vin ToBaining OBE MBE (died 1995) was one of the first six elected indigenous members of the colonial-era Legislative Council of Papua and New Guinea, between 1961 and 1963.
Subsequently, he was involved in the formation of the Pangu Party in 1967, which went on to form the government of Papua New Guinea (PNG) when the country became independent in 1975.
He was instrumental in the formation of the Tolai Cocoa Project in the 1950s, designed to improve the quality of cocoa-processing facilities for local farmers on the Gazelle Peninsula.
In 1967, nine members of the House of Assembly came together to form the Pangu Party, together with others that included Michael Somare, the future prime minister of an independent Papua New Guinea, and ToBaining, who became one of its four rotating chairmen.
Subsequently, he left the Pangu Party and became president of the newly formed Melanesian Independence Party, which had a policy of achieving independence for the islands of the Territory of Papua and New Guinea, specifically New Britain, New Ireland, Bouganville, and the Admiralty Islands.
