102 staff at Superquinn's support office in Lucan in Dublin will lose their jobs over the next 18 months.
This comes as its owner - the Musgrave group - said it will change the name of the Superquinn stores to Supervalu from next February. It added that the 2,500 staff who work in the Superquinn stores will not be affected.
The Musgrave group bought Superquinn out of receivership in July 2011 and took control of the business in October 2011 after approval from the Competition Authority.
Musgrave chief executive Chris Martin said that he understands that some customers will be sad to see the Superquinn name going.
''The decision follows a considered review of all options and is an inevitable next step given the realities of a totally changed grocery market and what the Irish consumer now needs,'' he added.
The group said it plans to invest €10m to complete the refurbishment of the Superquinn stores in its network.
