John Hamilton Gray, QC (1814 – June 5, 1889) was a politician in the Province of New Brunswick, Canada, a jurist, and one of the Fathers of Confederation. He should not be confused with John Hamilton Gray, a Prince Edward Island politician (and also a Father of Confederation) in the same era. As Premier, Gray led the Conservatives to victory in the June 1856 election on an anti-prohibition platform and repealed the liquor law. However, with the central issue uniting his government now resolved he became unable to command a majority in the legislature and resigned in May 1857.
