Lieutenant Colonel Robert Blair "Paddy" Mayne, DSO & Three Bars (11 January 1915 – 14 December 1955) was a British Army officer from Newtownards, capped for Ireland and the British Lions at rugby union, lawyer, amateur boxer, and a founding member of the Special Air Service (SAS). During the course of the Second World War, Mayne became one of the British Army's most highly decorated soldiers. He was controversially denied a Victoria Cross.
