Sir Ernest Clark, GCMG, KCB, CBE (13 April 1864 – 26 August 1951) was a British civil servant who served as Governor of Tasmania from 1933 to 1945.

After the war, he was appointed a Commander of the Order of the British Empire in the 1918 Birthday Honours, and joined the Board of Inland Revenue as assistant secretary and deputy inspector of taxes.

His friendship with James Hamilton, 3rd Duke of Abercorn, the Governor of Northern Ireland, also eased relations between the new Irish government and Downing Street.

[1] Clark visited Australia in 1928, as a member of a British government economic delegation tasked with examining the state of the Australian economy.

The post had been vacant since 1930 due to lack of funds, and Clark's appointment, with his background in finance and contacts in London business may aid both Tasmania and Australia.
