Queen Elsa of Arendelle: (also known as the Snow Queen) is the deuteragonist of Disney's 2013 animated feature film Frozen. She is the firstborn daughter of former monarchs King Agnarr and Queen Iduna, older sister of Princess Anna, and the contemporary ruler of Arendelle. Her powers over ice and snow ultimately led her to become the Snow Queen at adulthood.

Elsa is loosely based on the titular character of "The Snow Queen", a fairy tale by Hans Christian Andersen, and to a much lesser extent, Kai from the same story. While the character from the original fairy tale was neutral and, to some degree, villainous, Elsa was rewritten as a tragic heroine.
