Four by-elections to the Parliament of Vanuatu were held in 2009 to fill seven vacant seats.
The by-election was held in the constituency of Efate on 6 August 2009, after a Supreme Court ruling removed four MPs from Parliament because they had either used inducements to win their seats, or had won due to electoral irregularities.
The by-election was held in the constituency of Epi on 5 February 2009, after Leinavao Tasso was removed after being accused of bribing voters.
The by-election was held in the constituency of the Southern Islands on 15 December 2009.
The constituency covers four of the five islands of Tafea Province (Aniwa, Futuna, Erromango and Anatom, excluding only Tanna). It elects a single representative to Vanuatu. The by-election was due to the death of sitting MP Ture Kailo, of the Vanua'aku Party, who had died suddenly in October while attending a seminar organised by the Australian government in Canberra.
The seat was retained by the Vanua'aku Party; its candidate, Philip Charley, finished "well ahead" of the candidates from the Union of Moderate Parties and the National United Party.
The by-election was held in the constituency of Tanna on 30 April 2009, after a Supreme Court ruling removed Judah Issac after he was found guilty of bribery.
