Ralph John Regenvanu (born 20 September 1970 in Suva, Fiji) is a ni-Vanuatu anthropologist, artist and politician. He has been a Member of Parliament since September 2008, a member of Cabinet for most of the period since December 2010, and was the Director of the Vanuatu National Cultural Council from 1995 until December 2010.
He has been a leading figure in Vanuatu's cultural world, primarily as a promoter of cultural knowledge preservation and sustainable development as a researcher, but also, to a lesser extent, as a painter and illustrator. He has represented Vanuatu and its culture in the international sphere, notably through UNESCO. His transition to politics came suddenly in 2008, at a comparatively young age; his successful campaign to be elected to Parliament generated popular and media support.
As a Member of Parliament, he sought to publicise his activities and discuss political issues directly with members of the public; he also used his parliamentary allowance to help finance student scholarships and youth business projects. Three months after his election, he was arrested and charged with aiding prisoners who had escaped from gaol. The charges were later dropped. In late 2010, he launched his own political party, shortly before being appointed to Cabinet.
