John Munn (12 March 1788 – 20 March 1859) was a Scottish-born shipbuilder and political figure in Lower Canada. He was born in Irvine, Scotland in 1788, the son of a sailor, also named John Munn, and came to Quebec City in 1801, where he began his career as a shipbuilder. In 1814, he went to Montreal, where he manufactured ships for the government. He set up his own shipbuilding business at Quebec in 1815. Many of the ships that he built were transported to Britain for sale. Munn, well known as a master craftsman, also trained a number of shipbuilders. He also helped found Queen's College at Kingston.
