Donegal has so far made 228 pledges to the Irish Red Cross to accommodate refugees from Ukraine.
There have been almost 12,000 pledges of accommodation from across the country.
On Monday, the Government announced an accommodation pledge register through the Irish Red Cross website.
Three quarters of the offers are for shared accommodation where people have a room to spare.
Cash donations have reached €14m.
A spokesperson for the Irish Red Cross said “The Irish Red Cross have been blown away by the generosity of the Irish people both from an accommodation pledge point of view and for donating money, they have been simply astonishing.
“We are asking those who have registered with us with offers of accommodation to bear with us and our contact team will be in touch over the coming weeks. We have almost 12,000 pledges of accommodation since just last Friday when we had just 180 offers and to out it in context it took a few months to reach 1,000 pledges during our Syrian refugee campaign a few years ago.
“The Irish business community have also come onboard our Ukraine crisis appeal in great numbers with more and more calling us everyday to offer help and so far over 125 companies have been in touch with our fundraising team and then so many community groups have also been reaching out to us about their fundraisers. We are just so grateful to such a wonderful reaction from the Irish people so far.”
A spokesperson has asked that those who have registered offers of accommodation “to bear with us and our contact team will be in touch over the coming weeks”.
The highest number of accommodation pledgers by county is 2,149 in Dublin, followed by 1,327 in Cork, and 663 in Galway.
