George Henry Millar (fl. 1780 - 1790) was a British engraver and map publisher active in London during the latter part of the 18th century. Millar published the 1782 New and Universal System of Geography. He is also credited with an early view of the 1775 Battle of Bunker Hill. Most of his work was published between 1782 and 1785, and we have found no earlier or later productions.
