Martin's Food Markets is a chain of supermarkets operating in Maryland, Virginia, West Virginia and western Pennsylvania. Like Giant stores, they are operated by Giant-Carlisle and are owned by Ahold Delhaize. The stores are generally identical to Giant-Carlisle stores. In 1998, when Ahold purchased Giant-Landover, some Martin's stores were closed and sold to other chains to comply with Federal Trade Commission regulations. These locations included stores in Frederick, Carroll, Harford and Cecil counties in Maryland, where the Giant of Landover name was seen as more dominant. However, two stores in this area, in Eldersburg and in Rising Sun, were not sold and continue to operate as Martin's to this day.
