The name Karena is a girl's name of Scandinavian origin. Karena and is often added to user-created lists like Ballet Names and discussed in our forums with posts like "The Makeover Baby Name Game".
From the experts:
Karena modernizes middle-aged Karen but also creates pronunciation confusion. Is it ka-REN-a, ka-REEN-a, or just plain Karen with an a at the end? Spelled Karenna as in Gore goes partway toward clarifying things.
