The 65-year-old will succeed Susan Denham
The Government has named Frank Clarke as its pick to become the new Chief Justice.
The 65-year-old will succeed Susan Denham, whose tenure will end when she retires next month.
Mr Justice Clarke has been on the bench for five years and will become the 12th Chief Justice in the history of the State.
He has been nominated today after an expert group provided a shortlist of three names to the Department of Justice.
Though sources said only one name had been presented to ministers for approval.
The Chief Justice of Ireland is the President of the Supreme Court, and titular head of the judiciary - the judicial arm of Government.

He was educated at Drimnagh Castle CBS and University College Dublin - where he was awarded a BA in Mathematics and Economics.
Having completed his legal studies at King's Inns, he was called to the Bar in 1973.
He practised at the Bar from then until his appointment to the High Court in November 2004.
While a judge of the High Court, he served as chair of the Referendum Commission in relation to the second referendum on the Lisbon Treaty.
He was mainly assigned to the Commercial List of the High Court.
He was appointed to the Supreme Court in March 2012.
