Tesco stores in Hexham are inviting customers to round up their bill to the nearest pound at the checkout for one week in July and another week in August.
The supermarket is asking customers to participate to support food charities FareShare and the Trussell Trust during the summer holidays, when child hunger can be an issue.
The Kids Free initiative in the stores' cafes will also be running during the holidays, and the supermarket is set to expand its pre-packed customer donation bags to stores in the North East.
Claire De Silva, head of communities at Tesco, said: "If we all pull together over the coming months, whether that’s popping a few tins into a food collection point, picking up a food donation bag in our stores or rounding up our grocery bill, we can make a difference to the lives of thousands of children, who, without support, could have a tough summer holiday."
In addition to the customer-focused initiatives, Tesco is directing a £1 million donation to FareShare and the Trussell Trust.
George Wright, chief executive at FareShare, said: "This generous donation from Tesco will ensure we continue providing vital support to charities that rely on FareShare food to strengthen their local communities this summer."
