Vaccinated passengers will no longer need to have a negative COVID-19 test result to enter Ireland.
Taoiseach Micheál Martin has confirmed ministers have agreed to ease the rule.
The testing requirement was introduced in December, as part of efforts to curb the spread of the Omicron variant here.
Anyone flying into Ireland from overseas needed to have proof of either a negative PCR or antigen test before arrival, regardless of their vaccination status.
However, with the Omicron strain now thought to be responsible for 96% of cases in Ireland, Cabinet has agreed to scrap the rule.
A return to previous digital COVID cert rules means anyone who is fully vaccinated or recently recovered from COVID-19 can enter the country without the need for a test.
However, those who aren't vaccinated will still need proof of a negative test result, as per the rules in place pre-December.
Last month, the Government also lifted strict travel rules that were in place for the southern African countries where Omicron was first identified.
The Government said all the travel rules were temporary and would be kept under constant review.
