Frances Jennifer Adamson, is an Australian public servant and diplomat who is the 36th Governor of South Australia, in office since 7 October 2021. She previously served as Australian Ambassador to China from 2011 to 2015 and as secretary of the Department of Foreign Affairs and Trade from 2016 to 2021.

The governor of South Australia is the representative in South Australia of the monarch, currently King Charles III. The governor performs the same constitutional and ceremonial functions at the state level as does the governor-general of Australia at the national level. In accordance with the conventions of the Westminster system of parliamentary government, the governor nearly always acts solely on the advice of the head of the elected government, the premier of South Australia. Nevertheless, the governor retains the reserve powers of the Crown, and has the right to dismiss the premier. As from June 2014, Queen Elizabeth II, upon the recommendation of the premier, accorded all current, future and living former governors the title 'The Honourable' for life. The first six governors oversaw the colony from proclamation in 1836, until self-government and an elected Parliament of South Australia was granted in the year prior to the inaugural 1857 election.
