Ham Lini (born 1951?) is a politician in Vanuatu, who currently serves as Prime Minister of that country (since December 11, 2004). He is the brother of Walter Lini, one of the founders of Vanuatu. Ham Lini is the leader of the National United Party, which in the July 2004 parliamentary elections became the largest party in parliament, with 10 of 52 seats. He became a candidate for Prime Minister, but he was defeated by Serge Vohor, though Lini also had the support of the largest faction of the Vanu'aku Party, led by outgoing Prime Minister Edward Natapei. He continued to dispute the results and lead the opposition to the Vohor government until August 20, 2004, when Vohor and Lini formed a National Unity Government, in which Vohor remained Prime Minister and Lini became Deputy Prime Minister and Minister of Internal Affairs. In December 2004, Vohor was ousted in a no confidence vote for unilaterally establishing relations with Taiwan (Republic of China), and Lini was elected prime minister by the parliament. He is an MP from Pentecost Island in Penama.
