General Sir Archibald James Murray, GCB, GCMG, CVO, DSO (23 April 1860 – 21 January 1945) was a British Army officer who served in the Second Boer War and the First World War. He was Chief of Staff to the British Expeditionary Force (BEF) in August 1914 but appears to have suffered a physical breakdown in the retreat from Mons, and was required to step down from that position in January 1915. After serving as Deputy Chief of the Imperial General Staff for much of 1915, he was briefly Chief of the Imperial General Staff from September to December 1915.
