Noël Treanor (25 December 1950 – 11 August 2024) was an Irish Roman Catholic prelate who served as Apostolic Nuncio to the European Union with the personal title of archbishop from 2022 until his death in 2024.

[1] He was recalled to the Diocese of Clogher in 1980, where he received his first diocesan assignment as assistant in the cathedral parish of Monaghan and Rackwallace, with responsibility for the local Catholic marriage advisory council.

While deeply involved in the expanding endeavour of COMECE to project Christian values into the European process, Treanor continued to engage in pastoral work through contact with the local English-speaking community.

Treanor cited his experience with COMECE in assuring an Oireachtas committee that ratification of the treaty would not affect Irish sovereignty over issues such as abortion and military neutrality.

New pastoral communities were drafted and presented to clergy in three meetings and subsequently to the lay faithful, with a regular practice rate of 20% across the diocese significantly influencing future structures, leading to increased sharing of personnel, skills and finances.
