Mooney is an Irish surname that originates from the Gaelic patronymic Ó Maonaigh, meaning 'descendant of Maonach'. The personal name Maonach itself derives from maoin, a word that denotes 'wealth' or 'treasure'. This etymology indicates that the original bearer of the name was regarded as wealthy, treasured or beloved within the community.

In the medieval period the name was recorded as OʹMaonaigh, with the prefix Oʹ signalling a male descendant. Over the centuries a number of orthographic variants have appeared, including OʹMooney, Meeny, Meany, Mooney, Money and OʹMoeney. These variations reflect the changing conventions of spelling across different regions and epochs.

Four distinct septs bearing the name Mooney can be identified within Ireland. The first sept originated in the parish of Ardara in County Donegal and is linked to the ecclesiastical community of the Diocese of Raphoe. This branch claims descent from Monach, son of Ailioll Mor of Ulster, and held church property for successive generations. The second sept, situated in County Offaly, served as custodians of the shrine of St. Monahan in the parish of Lemanaghan and gave name to the townland of Ballymooney. The third sept is located in County Sligo, where four townlands called Ballymeeny in Easky attest to its presence. The fourth sept was situated in Munster, where the name appears in a modern form as Mainey.

The earliest surviving documentary spelling of the family name is that of Father Donagh Mooneyin, who is recorded in 1615 as the Provincial of the Irish Franciscans. He performed the important duty of acting as official guardian to the young Earls of Tyrone and Tyrconnell while they were in exile at Louvain during the reign of King James I of England and VI of Scotland (1603–1625).

The Mooney surname remains primarily associated with Ireland. It is borne by individuals who trace their ancestry to the original bearer of the name and continues to be recognised as an integral part of Irish cultural heritage.

This surname reflects a Celtic origin within the broader context of Christian societies in the British Isles, with Gaelic language influences that have been preserved in its orthography and terminology. The prefix Oʹ, the root word maoin, and the use of the Gaelic term Ó all signify the enduring heritage of the name and its connection to the ancient Irish patrimonial system.
