Irish Brazilians (Portuguese: Irlando-brasileiros or Hiberno-brasileiros; Irish: Gael-Brasaíle) are Brazilian citizens of Irish ancestry, or Irish-born people residing in Brazil. Many Irish immigrants to Brazil changed their surnames to resemble Portuguese names more closely, often losing the common prefix 'O'.
