The Tánaiste says today is the beginning of the end of the Covid pandemic.
As of this morning there's no requirement for social distancing, restrictions on hospitality have lifted and there are no caps on gatherings in the home.
Live events can go ahead at full capacity, with Minister Catherine Martin confirming there will be St Patrick's Day parades this year.
Health officials say there WILL be a rise in Covid cases as a result of the reopening but believe it can be managed.
Tánaiste Leo Varadkar says today is a significant day:
"It's been a very long two years and this pandemic has brought tragedy to our nation. Over 9000 lives lost on the island of Ireland, north and south. But today is a day hope, a good day and a day to look forward cautiously to a spring and summer of freedom. Knowing that there will be bumps in the road ahead, but confidence that if this is not the end, it is certainly the beginning of the end."
