What is the meaning of the name Fianna ?

The baby name Fianna is a Female name , 3 syllables long and is pronounced /ˈfiːənə/ or /fiˈænə/ (FEE-ə-nə, fee-AN-ə).

Fianna is Irish in Origin.

Fianna is an Irish Gaelic given name taken from Old Irish fíana, the plural of fían, ‘a band of young warrior-hunters.’ In myth it names the roving warbands led by Fionn mac Cumhaill in the Fenian Cycle, so the modern name carries connotations of bravery, independence, and loyal comradeship rather than a single literal gloss.

As a personal name it is a recent revival: scarcely recorded before the late 20th century, it has since seen modest use in Ireland, Britain, and the Irish diaspora, primarily for girls. The term remains culturally visible in modern Irish institutions (e.g., Fianna Fáil; Na Fianna Éireann), which has helped keep it familiar. Variants and spellings include Fiana and Fiannah; nicknames include Fia and Fi. Not to be confused with Fiona or Fíadh, which are etymologically unrelated.
