Sir Edward Howard Marsh (18 November 1872 – 13 January 1953), born to Professor Howard Marsh of Downing College, Cambridge, was a British polymath, translator, arts patron and civil servant. He was the sponsor of the Georgian school of poets and a friend to many individuals, including Rupert Brooke and Siegfried Sassoon. In his career as a civil servant he worked as Private Secretary to a succession of Great Britain's most powerful ministers, particularly Winston Churchill.

A classical scholar and translator, Marsh edited five anthologies of Georgian Poetry between 1912 and 1922, and he became Brooke's literary executor, editing his Collected Poems in 1918.

In addition to his work editing Churchill's writing while the latter was in or out of government, Marsh introduced Siegfried Sassoon to Churchill as a means of aiding the former's career.
