Atlantic Giant is a recent label for the roun phenotypes of the giant squash (popularly called a pumpkin, depending upon fruit color) variety of the species Cucurbita maxima that was bred publicly from simple Hubbard material through intermittent efforts over the past centuries. The uniqueness of this variety lies in its production of fruits more massive than those produced by any other plant in the world. Fruit can exceed 16 feet in circumference. The heaviest Atlantic Giant on record weighed 766 kg (1689 lb) and was grown by Joe Jutras in 2007. Under normal conditions the Atlantic Giant can consistently produce fruits in excess of 250 kg (551 lb).
