Maonaigh is Irish in Origin.

Maonaigh is an Irish Gaelic given name deriving from the noun maoin “wealth, treasure,” via the early personal name Maonach, yielding the sense “wealthy, prosperous” or “man of treasure.” The -aigh ending mirrors the form preserved in surnames (Ó Maonaigh) and is commonly approximated in English as “MOO-nee.”

The name is best attested through the hereditary surname Ó Maonaigh, borne by several unrelated medieval families, especially in Leinster and Ulster, and later anglicized as Mooney and O’Mooney. As a standalone forename, Maonaigh is a modern revival shaped by Irish-language orthography and cultural renewal; it remains rare but recognizably Gaelic. Variants and related forms include Maonach (the earlier nominative personal name), the surname form Ó Maonaigh, and the anglicized Mooney/O’Mooney. Related vocabulary from the same root includes maoineach, meaning “wealthy.”
