Centra is a convenience shop chain that operates throughout Ireland. The chain operates as a symbol group owned by Musgrave Group, the food wholesaler, meaning the individual shops are all owned by individual franchisees. The chain has three different formats available to franchisees—smaller Quick Stop outlets, mid-sized Foodmarkets, and larger Supermarkets. The majority of the shops follow the Quick Stop format, or are simply branded Centra, as Musgrave also offers the SuperValu format, which is geared towards larger supermarkets. .
