A leadership election in the Liberal Party of Australia, the party of government in the Parliament of Australia, was held on 9 January 1968. It followed the disappearance and presumed drowning of previous leader Harold Holt, who had been declared dead on 19 December 1967. The contest was won by Senator John Gorton in a party room ballot; he was sworn in as prime minister the following day, replacing caretaker John McEwen.
