2025 Tristan da Cunha general election

The 12-member Island Council consists of the Administrator as President, three appointed members and eight elected members, who are elected by plurality-at-large voting. At least one elected member of the council must be a woman. If there are no women among the eight candidates that receive the most votes, only the top seven male candidates are declared elected, alongside the woman that received the highest number of votes. If there are no female candidates, a by-election is held for the eighth seat, in which only female candidates can stand.^[2][3]

The Chief Islander is elected on a separate ballot by first-past-the-post voting, and must also be elected to the Island Council to be eligible to become Chief Islander.^[3]
