Helga (derived from Old Norse heilagr - "holy", "blessed") is a female name, used mainly in Scandinavia, Germany and Hungary (Hege, Helle, Helge, Helga, Helka or Oili). The name was in use in England before the Norman Conquest, but appears to have died out afterwards. It was re-introduced to English-speaking nations in the 20th century from Germany and the Nordic countries. Russian name Olga (Ольга) is derived from it. Scandinavian male equivalent is Helge, or Helgi.
