Fahy is Irish in Origin.

Fahy is an Irish Gaelic surname-turned-given-name from Ó Fathaigh, meaning “descendant of Fathadh.” The personal name Fathadh is very old; scholars variously derive it from fothadh, “foundation/support,” or from fáth, “reason, cause” (and by extension “prophecy”). These roots yield modern interpretive meanings like “steadfast foundation” or “one of insight.” Common English forms are Fahy, Fahey, and Fahie; the Gaelic spellings Ó Fathaigh (masculine) and Ní Fathaigh (feminine) survive in Ireland.

Ó Fathaigh families were prominent in Connacht - especially Galway, Clare, and Limerick - and appear in late medieval annals and early modern tax rolls. The Anglicized variants spread widely through emigration, with Fahie appearing in British and Caribbean records. As a first name, Fahy is a rare modern adoption in English-speaking countries, fitting the trend of Irish surnames used as given names and functioning as gender-neutral. Related forms include O’Fahy/O’Fahey and the older given name Fathadh.
