John Thomas Lang, usually referred to as J. T. Lang during his career and familiarly known as "Jack" and nicknamed "The Big Fella", was an Australian politician, mainly for the New South Wales Branch of the Labor Party. He twice served as the 23rd Premier of New South Wales from 1925 to 1927 and again from 1930 to 1932. He was dismissed by the Governor of New South Wales, Sir Philip Game, at the climax of the 1932 constitutional crisis and resoundingly lost the resulting election and subsequent elections as Leader of the Opposition. He later formed Lang Labor that contested federal and state elections and was briefly a member of the Australian House of Representatives.

The governor of New South Wales is the representative of the monarch, King Charles III, in the state of New South Wales. In an analogous way to the governor-general of Australia at the national level, the governors of the Australian states perform constitutional and ceremonial functions at the state level. The governor is appointed by the monarch on the advice of the premier of New South Wales, and serves in office for an unfixed period of time—known as serving At His Majesty's pleasure—though five years is the general standard of office term. The current governor is retired judge Margaret Beazley, who succeeded David Hurley on 2 May 2019.
