Old Irish · “Derived from the Old Irish word "niamh" meaning "bright" or "radiant". The name belongs to one of the most celebrated figures of Irish mythology, Niamh of the Golden Hair, a princess of Tír na nÓg (the Land of Eternal Youth) who fell in love with the poet-warrior Oisín and carried him away on her white horse across the sea.

Aoife

Old Irish · “Derived from the Old Irish "Aífe", itself from the word "oíph" meaning "beauty" (modern Irish "aoibh"). This ancient Irish name has been borne by several legendary figures, most notably a fierce warrior woman who engaged in single combat with the hero Cúchulainn, and a jealous queen in the tale of the Children of Lir who transformed her stepchildren into swans.

Brigid

Old Irish · “Derived from the Old Irish "Brigit" or "Bríg", meaning "exalted one" or "the high one", from a Proto-Celtic root "briganti" meaning "high, lofty, the exalted one". Brigid was one of the most important goddesses of pre-Christian Ireland, associated with poetry, healing, smithcraft, and the hearth fire. The Christianised Saint Brigid of Kildare (c. 451–525) became one of Ireland's three patron saints.

Catriona

Scottish Gaelic · “Scottish Gaelic form of Katherine or Catherine, derived from the Greek "Aikaterine", whose etymology is disputed but may relate to the Greek "katharos" meaning "pure".

More Irish names

Brennan

An Anglicised form of the Irish surname Ó Braonáin, meaning "descendant of Braonán", where Braonán is a diminutive of "braon" meaning "moisture", "drop", or "sorrow". The name is associated with Saint Brendan the Navigator (Naomh Bréanainn), the 6th-century Irish monk who, according to legend, sailed across the Atlantic to discover a western paradise. When used as a first name, it carries both the sorrow-drop etymology and the adventuring saint.

Roisin

Derived from the Irish word "rós" meaning "rose" combined with the diminutive suffix "-ín", giving the full meaning "little rose". The name carries deep cultural significance in Irish tradition through the poem "Róisín Dubh" (Dark Little Rose), a 16th-century allegorical poem in which Ireland is personified as a dark-haired girl — a coded political metaphor that persisted through centuries of occupation.

Nollaig

Derived from the Old Irish word for Christmas, itself from the Latin "natalicia" (nativity). The name is given to children born around Christmas time and has an endearing seasonal quality specific to Irish culture. It reflects the long tradition of Irish naming practices tied to the liturgical calendar.

Éabha

The Irish form of Eve, from the Hebrew "Chavah" meaning "living" or "life-giver". In Irish Gaelic the name takes the form Éabha, pronounced quite differently from the English Eve, and has been used in Ireland since the early Christian period. In Irish tradition Éabha (Eve) is also associated with various legendary and mythological figures, and the name enjoyed a significant revival in Ireland during the twentieth-century Gaelic language revival.

Mairéad

The Irish form of Margaret, from the Greek "Margarites" meaning "pearl". Mairéad is the native Irish-language version of the name, distinct from the borrowed anglicised "Margaret" and carrying a distinctly Irish-Gaelic identity. The name has been borne by Mairéad Corrigan Maguire, the Northern Irish peace activist who co-founded the Community of Peace People and was awarded the Nobel Peace Prize in 1976.

Torin

Derived from the Irish/Scottish Gaelic "tòrr" meaning "a hill" or "a high craggy place", with a suffix giving the meaning "from the hill" or "hill chief". The name has a rugged, topographic quality common in Gaelic naming traditions, where the landscape itself shapes identity. It is used in both Irish and Scottish Gaelic contexts as a strongly masculine name associated with highland geography.
