Hugh Macdonald, PC (May 4, 1827 – February 28, 1899) was a lawyer, judge and member of the First Canadian Parliament. He represented the Antigonish riding of Nova Scotia, from 1867 to 1869, along with William Hallett Ray, as an Anti-Confederate and, from 1869 to 1873, as a Liberal-Conservative. MacDonald served as President of the Queen's Privy Council for Canada and Minister of Militia and Defense in 1873. Later that year, he resigned his seat in parliament to accept an appointment to the Nova Scotia Supreme Court.
