Michael John Ahern (born 2 June 1942) is a former Queensland National Party politician who was Premier of Queensland from December 1987 to September 1989.
After a long career in the government of Sir Joh Bjelke-Petersen, Ahern became his successor amid the controversy caused by the Fitzgerald Inquiry into official corruption.
Ahern's consensus style and political moderation contrasted strongly with Bjelke-Petersen's leadership, but he could not escape the division and strife caused by his predecessor's downfall.
