Sir George Warburton Fuller KCMG (22 January 1861 – 22 July 1940) was an Australian politician who served as the 22nd Premier of New South Wales, in office from 1922 to 1925 and for one day in December 1921.

He was Minister for Home Affairs in 1909 and 1910 in Alfred Deakin's Commonwealth Liberal Party government and was responsible for making Canberra the national capital.

In the part of 1916 and 1917, he was a leader of New South Wales' Nationalist Party and he became Colonial Secretary (the second most important cabinet position) in 1916.

His promise of higher pay and improved seniority benefits to workers returning to work split the rail unions for most of the twentieth century and the different employment conditions lasted until the Lang Government was elected.

[citation needed] Shortly after Lang's victory, Fuller resigned from the Nationalist leadership in favour of Thomas Bavin.
