Blair Anderson Wark VC, DSO (27 July 1894 – 13 June 1941) was an Australian recipient of the Victoria Cross, the highest decoration for gallantry "in the face of the enemy" that can be awarded to members of the British and Commonwealth armed forces.
A quantity surveyor and member of the Citizens Military Force, Wark enlisted in the Australian Imperial Force on 5 August 1915, for service in the First World War. After initially being employed in the defence of the Suez Canal, his battalion was shipped to the Western Front; it was here that Wark would be twice decorated for his bravery and leadership.
Having received the Distinguished Service Order in 1917 for his actions at Polygon Wood, Wark was awarded the Victoria Cross in 1918 for his leadership and gallantry when in temporary command of his battalion over a three-day period, while conducting operations against the Hindenburg Line.
