John Strange (September 2, 1788 – October 14, 1840) was a merchant and political figure in Upper Canada.
At the close of the war, John settled in Kingston and became Major in the First Regiment of the Frontenac Militia.
In 1818, he married Mary McGill in Albany, New York (sister of his brother Maxwell's wife Elizabeth).
In the same year, he was elected to the Legislative Assembly of Upper Canada for Frontenac County.
He was originally buried in the Upper Burial Grounds (now McBurney Park in Kingston Ontario), and his remains later relocated to Cataraqui Cemetery.
