Duncan Gillies (14 January 1834 – 12 September 1903), was an Australian colonial politician who served as the 14th Premier of Victoria. Gillies was born at Overnewton near Glasgow, Scotland, where his father had a market garden. He was sent to the high school until he was about 14, when he entered an office in Glasgow. In 1852, he arrived in Melbourne and travelled to the goldfields at Ballarat, where he worked first as a miner and later as a businessman and company director. A portrait of Gillies by Josephine Muntz-Adams hangs in Parliament House Victoria.
