During the Easter break, one church in Denbigshire prepared 150 meals in one day for school children in Wrexham and Rhyl.
Dr Barry Morgan, the Archbishop of Wales, said: “Our churches are based in every community in Wales and it's realised that during holiday times there are children who are going hungry because these are children who have free school meals during term time, who have no food during the holiday period."
A spokesperson for the Church told BBC Radio Cymru’s Post Cyntaf show: “With no statutory provision in place to support children in holidays... feeding children during school holidays is falling to the voluntary sector."
An All-Party Parliamentary Group is urging the government to use money made from the upcoming sugar tax to fund a national programme of school holiday food provision.
The APPG on Hunger and Food Poverty recommends that a national programme backed by £200 million could all but eliminate child hunger during the school holidays.
