For over a decade, Disney fans around the world have been captivated by the adventures of Elsa and Anna in the magical kingdom of Arendelle. But one mystery remains unsolved: What are their last names?

As iconic characters, Elsa and Anna are beloved by fans of all ages. Knowing their surnames would deepen our understanding of their royal lineage and enrich the storytelling of the Frozen universe. While many Disney characters have full names, such as Fa Mulan, Elsa and Anna’s last names remain a mystery.

We, the fans, respectfully ask Disney to officially reveal the full names of Elsa and Anna in future films, series, or publications. Join us in solving this icy enigma and adding a little more magic to the Frozen legacy!

Sign this petition and let Disney know: the world deserves to know Elsa and Anna’s last names!

Addenda (6.27.2025):

Here are a few reasons why this petition matters:

• Every major character (Kristoff, Hans, and Mattias) has had their full names revealed, except Elsa and Anna.
• Anna will marry Kristoff and take on his surname of Bjorgman, but her maiden name is unknown.
• "Frozen: Polar Nights - Cast Into Darkness" includes a scene where Elsa and Anna use a census record book containing full names of everyone listed in it to find the name of a character crucial to solving the conflict (Stig Peters)
• In "Anna of Arendelle and the Silver Skates," the first story in the ten-story anthology novel "All is Found: A Frozen Anthology," Anna meets new friends at a winter festival while disguised as a boy.  To avoid giving away her true identity, she makes up the name "Anders Anderson."  So, in this case, she uses a fabricated surname for an alias, but we have no idea what her actual surname is.

We've had a great start to this petition.  Let's keep it going!  Please share this petition with others who are fans of the Frozen franchise!
