The Martin's name originates from a small chain based in Hagerstown, Maryland. Giant-Carlisle purchased Martin's while expanding in 1968. The name, once known only in Hagerstown, was expanded into nearby Waynesboro, Pennsylvania; Martinsburg, West Virginia; Frederick, Maryland; and Winchester, Virginia. The chain has since expanded further west into Maryland's Allegany County, into West Virginia's Jefferson and Mineral counties, into Virginia's Culpeper and Warren counties, and as far south as Petersburg, Virginia. The Martin's name was extended into west central Pennsylvania upon the purchase of corporate-owned Jubilee Foods stores; these stores use the Martin's banner instead of Giant to avoid confusion with Pittsburgh-based Giant Eagle, which has stores in many of those same markets. Martin's now operates stores in Altoona, Duncansville, Connellsville, Indiana, and DuBois. Despite these locations being located relatively close to Pittsburgh, the Connellsville location is the only store located within the Pittsburgh metropolitan area, and Martin's currently has no plans to further expand there, mainly due to Giant Eagle's tight grip on the market there.
