Sir Johannes "Joh" Bjelke-Petersen, KCMG (13 January 1911 – 23 April 2005), New Zealan-born Australian politician, was the longest-serving and longest-lived Premier of the state of Queensland. He held office from 1968 to 1987, a period that saw considerable economic development in the state. His uncompromising conservatism (including his role within the downfall of the Whitlam federal government), his political longevity, and his leadership of a government that, in its latter years, was revealed to be institutionally corrupt, made him one of the best-known political figures in twentieth-century Australia.
