William Dunstan, VC (2 March 1895 – 8 March 1957) was an Australian recipient of the Victoria Cross, the highest award for gallantry "in the face of the enemy" that can be awarded to members of the British and Commonwealth armed forces.

He was 20 years old and a corporal in the 7th Battalion, Australian Imperial Force during the First World War when he was awarded the VC for his actions on 9 August 1915, during the Battle of Lone Pine on Gallipoli, Turkey.

During the action Turkish forces had made a determined counter-attack on the centre of the newly captured trench held by a lieutenant, Frederick Harold Tubb, two corporals (Alexander Stewart Burton and Corporal Dunstan), and a few men.

After the war he worked for the Repatriation Department in Melbourne and in 1921 joined the staff of The Herald and Weekly Times as an accountant.

In 1995 a Memorial to Dunstan was erected in Sturt St, Ballarat, Victoria, Australia.
