Sir Charles Edward Mallet (2 December 1862 – 21 November 1947), was a British historian and Liberal politician. He was knighted in 1917.

He was the only son of the activist Louisa (born Udny) and Charles Mallet, a civil servant.^[1] He was educated at Balliol College, Oxford, and was admitted to Middle Temple on 21 May 1886. He was Called to the Bar on 3 July 1889.^[2]

He first stood for parliament at the 1900 General Election when he was the unsuccessful Liberal candidate for the Conservative seat of Salford West.^[3] Mallet was returned to Parliament for Plymouth in 1906.

In 1908 he was appointed as Parliamentary Private Secretary to Walter Runciman who was President of the Board of Education. In February 1910 Asquith was considering him as a possible Chief Whip but was dissuaded by the outgoing Chief Whip Jack Pease who felt he was out of sympathy with many leading Liberals over the Lords.^[4]

In March 1910 Prime Minister H. H. Asquith appointed him Financial Secretary to the War Office, a position he held until he was defeated in the December general election of the same year.^{[citation needed]} He sought a return to parliament at the 1917 Salford North by-election as a Coalition Liberal candidate but was defeated by an Independent Labour candidate.^[5] He did not contest the 1918 General Election. He was Honorary Secretary of the Free Trade Union.^[6]

He became a supporter of the official Liberal party that opposed the Coalition Government. He sought to make a return to parliament standing as Liberal candidate for South Aberdeen, in 1922 without success.^{[citation needed]}

He tried again in 1923 without success.

He had published two works on Liberal politicians; Mr Lloyd George, a Study (1930) and Herbert Gladstone, a Memoir (1932).^[9]

His book on Lloyd George was entirely devoted to the shortcomings of the Liberal Leader.^[10]
