Christopher William Vane, 10th Baron Barnard CMG, OBE, MC, TD (28 October 1888 – 19 October 1964) was a British peer and military officer.
Lord Barnard was born on 28 October 1888 as the second son of Henry de Vere Vane, 9th Baron Barnard and the Lady Catharine Sarah Cecil, daughter of the 3rd Marquess of Exeter at Barnard Castle in County Durham.
Following in the footsteps of his father, he attended Eton College, but unlike many of his ancestors studied at Trinity College at the University of Cambridge for a B.A. rather than attending the University of Oxford.
Upon the completion of his degree, he entered the armed services, participating in World War I as a Major in the Westmorland and Cumberland Yeomanry in which he was awarded the Military Cross and wounded in action twice. His eldest brother, the Hon. Henry Cecil Vane, heir apparent to the barony of Barnard, also served in the Great War but was subsequently wounded and died of those wounds shortly thereafter, leaving his younger brother heir apparent to the title of Baron Barnard.
In 1922, Lord Barnard gained the rank of Major in the 6th Battalion of the Durham Light Infantry and served with distinction in the battalion until 1931.
