General Sir Neil Methuen Ritchie, GBE, KCB, DSO, MC, KStJ (29 July 1897 – 11 December 1983) was a senior British Army officer who saw service during both the First and Second World Wars. He commanded the Eighth Army in the North African Campaign until being dismissed in June 1942. Returning to England, he later commanded the 52nd (Lowland) Infantry Division and led XII Corps in the campaign in Northwest Europe from June 1944 until May 1945.
Following Lancing and the Royal Military College, Sandhurst, Ritchie's military career started in 1914 when he was commissioned as a second lieutenant into the Black Watch (Royal Highland Regiment). During the First World War he served with the British Expeditionary Force (BEF) in Belgium and France, where he was awarded the Distinguished Service Order in 1917, and later in the Mesopotamian campaign, in which he won the Military Cross in 1918, for "a fine example of coolness, courage and utter disregard of danger".
