Fergus Jago Smith (8 June 1843 – 25 January 1924) was an Australian politician.
He was born at Gulgong to John Smith, a chemistry professor and later politician, and Mary Tom. He attended The King's School in Parramatta, and after a world tour worked on his father's station at Molong and then on another station near Bathurst which he later owned. In 1887 he was elected to the New South Wales Legislative Assembly as the Free Trade member for West Macquarie. He did not re-contest in 1889. In 1895 he was appointed to the New South Wales Legislative Council, where he remained until his death at Bathurst in 1924. He was a brother-in-law to fellow politicians Charles Barton and Sir Joseph Innes.
Smith married Emily Grace Machattie on 25 January 1866. Their daughter Kathleen Marion Jago-Smith was the wife of Lieutenant-Colonel Chetwynd Rokeby Alfred Bond, who served in the Indian Staff Corps.
