Sir Hew Francis Anthony Strachan, CVO, DL, FRSE, FRHistS, FBA (/strɔːn/ STRAWN; born 1 September 1949) is a British military historian, well known for his leadership in scholarly studies of the British Army and the history of the First World War.

He was educated at Rugby School, then in 1968 was a merchant seaman for three months, working his passage around the world on ships of Ben Line Steamers Ltd.

In 1975, Strachan was elected a research fellow of Corpus Christi College, and in 1977–1978 was a senior lecturer in war studies at the Royal Military Academy Sandhurst.

[2] He was director of the Oxford Programme on the Changing Character of War from 2004 to 2015, and published a series of important articles on strategy, as well as editing books which have arisen from the project.

From 20 May 2014 to 28 August 2024, Strachan served as Lord Lieutenant of Tweeddale, in succession to Captain David Bingham Younger.

His impact produces histories of the Great War that are global and multi-dimensional, while rooted in the detail of military operations.

[7] In January 2014, Strachan told The Daily Beast that President Barack Obama's failures in Afghanistan and Syria have shown that he is "chronically incapable" of military strategy.

He said, "Bush may have had totally fanciful political objectives in terms of trying to fight a global War on Terror, which was inherently astrategic, but at least he had a clear sense of what he wanted to do in the world.
