The Giant Company is an American supermarket chain that operates stores in Pennsylvania, Maryland, Virginia, West Virginia, and Washington, D.C.. The chain operates full-scale supermarkets under the Giant and Martin's banners along with small-scale urban stores under the Giant Heirloom Market banner. Giant is a subsidiary of Netherlands-based Ahold Delhaize, which also owns similarly-named Giant Food of Landover, Maryland, often known as Giant-Landover; to distinguish from that chain, whose stores also operate under the Giant banner (albeit with a different logo), Giant Food Stores are often referred to as Giant-Carlisle or Giant/Martin's. A significant difference between the two chains is that Giant-Landover is unionized while Giant-Carlisle is non-union, with the exception of stores in Lewistown and Burnham, Pennsylvania.\n\n
