Alexander Grant (20 May 1734 – 8 May 1813) was a Royal Navy officer, businessman, and politician in Upper Canada. During his service with the Royal Navy Grant saw action in the Seven Years' War before becoming a naval superintendent. He then embarked on a career in the ship building industry before losing much of his wealth during the American Revolution. Grant recovered, however, and rose to prominence in civil society, becoming the administrator of Upper Canada in 1805.
