Lise Thibault DStJ (French pronunciation: [liz tibo]; born 2 April 1939) is a Canadian politician who served as the 27th Lieutenant Governor of Quebec from 1997 to 2007.

[1] She was closely associated with the federal Liberal Party for many years, and on the advice of Prime Minister Jean Chrétien, the Governor General appointed her Lieutenant-Governor of Quebec, following the resignation of Jean-Louis Roux in 1997.

She was criminally charged for offences involving fraud, breach of trust, forgery and fabrication of false documents related to the misspending of public funds during her ten years in office.

[9] In September 2015 she was sentenced 18 months in jail and was ordered to repay the government $300,000 ($200,000 to Ottawa and $100,000 to Québec) after pleading guilty to fraud and breach of trust in 2014.

[10] Judge Carol St-Cyr outlined her crimes, pointing out that she "took advantage of holes in the system and abused her position of authority to pay for trips, golf lessons and birthday parties... [and] forgot that her role as lieutenant-governor was to be a good example for Quebecers.
