The Garda Commissioner has been granted a two-year extension.
Drew Harris can now remain in the position as head of An Garda Síochána until September 2025.
The two-year extension was approved by the Cabinet this morning.
There had been speculation that Mr Harris could have been a contender for the position of head of the Metropolitan Police in Britain, following the resignation last week of former police commissioner Cressida Dick.
Mr Harris is the first person to be appointed Garda Commissioner from outside the force.
He previously served as Deputy Chief Constable of the Police Service of Northern Ireland.
He joined An Garda Síochána on a five-year €250,000 per annum contract in 2018, which was due to expire next year.
Public sector pay agreements have brought his current salary to over €270,000.
The extension was granted on foot of proposals brought by the Minister for Justice this morning.
In a statement this afternoon, Mr Harris said he was delighted to have his term extended.
"It is a great privilege and honour to be Garda Commissioner," he said.
"During the last four years, the organisation has made great progress in becoming an efficient and effective human-rights focused policing and security service.
"In particular, the work by garda personnel during the Covid-19 pandemic was a real demonstration of the organisation's commitment to keeping people safe through our ethos of policing by consent and in partnership with communities.
"However, while we have made many significant changes to the organisation in recent years, the pandemic also meant that we had to put on hold some of the elements of our reform programme that we had planned to introduce.
"I look forward to leading An Garda Síochána in providing the best possible policing and security service to the people of Ireland."
