Florence "Flo" Isabel, Lady Bjelke-Petersen (born 11 August 1920) is an Australian retired politician and writer. She was a member of the Australian Senate from 1981 to 1993, and is the widow of the longest-serving Premier of Queensland, Sir Joh Bjelke-Petersen.
Born as Florence Isabel Gilmour in Brisbane, she was employed as private secretary to the Queensland Commissioner for Main Roads when she met Johannes Bjelke-Petersen, who was then a Country Party member of the Legislative Assembly of Queensland. They were married on 31 May 1952.
Bjelke-Petersen was preoccupied with home duties until well after Joh Bjelke-Petersen became Premier in 1968. In the 1970s, however, she assumed an increasingly public role, as part of the Queensland National Party's increasing promotion of a Bjelke-Petersen "personality cult." Her homely sayings and her recipes for pumpkin scones were quoted in the media.
At the 1980 federal election, Joh Bjelke-Petersen arranged against the wishes of Party President Sir Robert Sparkes for his wife to be placed in the Number 1 position on the National Party's Queensland Senate ticket, ensuring her election. Her term was due to commence on 1 July 1981, but on 6 February 1981, Queensland Senator Glen Sheil resigned, creating a casual vacancy. She was appointed on 12 March 1981 for the remainder of Sheil's term, and then continued into her own term. It was speculated that her husband, Joh Bjelke-Petersen, intended entering federal politics, and that at some point Florence would resign from the Senate to allow Joh to be appointed to the vacancy. But Joh Bjelke-Petersen's federal aspirations ended with the failed "Joh for Canberra" campaign in 1987.
When Joh Bjelke-Petersen was knighted in 1984, Flo Bjelke-Petersen became Lady Bjelke-Petersen, and was officially known as "Senator Lady Bjelke-Petersen." She was frequently, but incorrectly, referred to as "Lady Florence" or "Lady Flo". (This usage suggests she is the daughter of a peer rather than the wife of a knight.) Although the name "Lady Flo" is incorrect, it has been almost universally used in the media and among the general public.
In Canberra Lady Bjelke-Petersen was well liked by politicians of all parties, even those who loathed her husband. Her speeches were usually about local Queensland issues and seldom political in content.
