The Justice Minister says Ireland could be accepting anything up to "tens of thousands" of Ukranian migrants.
She's in Brussels today to meet with other EU Justice Ministers, to discuss a coordinated response to managing the high volume of refugees entering EU countries.
The UN estimates one million people have now fled Ukraine into neighbouring countries, describing it as "the fastest movement of refugees anywhere in the world this century".
Helen McEntee will be pushing for initiatives that would allow Ukrainians get one year citizenship in Ireland, with extensions for up to three years.
Minister McEntee says she doesn't want to put an exact figure on the number of people that will come to Ireland.
"The most important thing for us is to make sure our doors our open."
Back at home, Government Ministers will meet to discuss how many refugees Ireland might take in and where they will be housed.
