Ms Justice Mary Irvine has been nominated by the Government as President of the High Court.
The nomination was approved by ministers at today's Cabinet meeting at Dublin Castle.
Currently, a judge of the Supreme Court, Ms Justice Irvine will be formally appointed to the position by President Michael D Higgins.
Ms Justice Irvine will be the first woman to be nominated for this role.
The position will become vacant when Mr Justice Peter Kelly retires on 18 June.
The Law Society of Ireland has welcomed today's nomination.
Law Society President Michele O' Boyle said: "I welcome in the warmest of terms this nomination of Ms Justice Mary Irvine both as an outstandingly able judge and as the first woman in history to hold this absolutely key role in the Irish judiciary.
"She will bring the qualities of independence, deep legal knowledge and insight that have characterised her distinguished career as a judge."
