Victoria Kerstin Heider-Leigh (born 1 January 1989), known professionally as Victoria Heider, is an English-German actress. After several television roles and acclaimed turns on the London stage, she rose to fame as Ygritte in the HBO fantasy series Game of Thrones. Heider achieved global recognition and acclaim for her role as painter Gerda Wegener in The Danish Girl, for which she received the Academy Award and Screen Actors Guild Award for Best Supporting Actress, among others.

Heider was born in Bonn, West Germany. Her father, William Leigh, is a career British diplomat (and current British Ambassador to Norway) who was First Secretary at the British Embassy in Bonn at the time he met her mother, German photographer Kerstin Heider. They later had another child, son Christoph (b. 2004 in London). Heider spent much of her childhood moving between London, during her father's postings at the Foreign and Commonwealth Office, and other parts of Europe (including Paris, Edinburgh, and Rome). She was educated primarily at international schools, and came to love performing as a means of socializing with new friends at new schools whenever she moved. When she completed her secondary education, she was accepted to a bachelor of arts program at the prestigious London Academy of Music and Dramatic Art (LAMDA) to study professional acting, and simultaneously began auditioning for guest parts on television, to moderate success.

After graduation from LAMDA, Heider went on to a highly-praised London stage debut in The Acid Test at the Royal Court. Shortly thereafter, she was cast in the popular HBO fantasy series Game of Thrones, and for her role as the wildling Ygritte in seasons two, three, and four, Heider was met with major acclaim. While on Game of Thrones, Heider also made return appearances on the London stage, as well as making simultaneous feature film debuts at the 2013 Toronto Film Festival in Bill Condon's The Fifth Estate and Amma Asante's acclaimed Belle.

Across 2014 and 2015, Heider had roles in six films and two stage productions. The most highly-praised was her portrayal of painter Gerda Wegener in Tom Hooper's The Danish Girl, for which she won the Academy Award for Best Supporting Actress. She followed up these banner years with her New York stage debut, in the transfer of the acclaimed London staging (in which she also participated) of A Streetcar Named Desire opposite Gillian Anderson and Ben Foster. In 2016 she also returned to television as Anne Neville in the second cycle of the BBC's acclaimed The Hollow Crown anthology, and will again be on British television screens in 2017 as part of the Cormoran Strike mystery series, before setting her sights on a galaxy far, far away as part of the Star Wars Han Solo spinoff film.

Victoria is an adventurous spirit and loves to travel, qualities she's inherited from her father and through her childhood spent largely abroad, but she is also classically trained and an old soul. She loves to explore new cities and visit art museums, the opera and ballet, and eat her way through wherever she travels (often by herself). She has been open with friends and family about struggling to come to terms with a one-two punch of seemingly overnight fame and success (first with Game of Thrones, and then with her Oscar win and great acclaim for The Danish Girl), and has taken to often staying at her parents' home in London or visiting them at her father's current station in Oslo when she is not working.

As a child who grew up going to one international school after the next, Victoria is about as gregarious as a naturally shy person can be, and enjoys making new friends and acquaintances even if it may not seem that way at first; her quietness can seem like disinterest, but she's an introverted extrovert who enjoys listening and absorbing new people and experiences. She's an active runner and kickboxer, and maintains a daily yoga and meditation practice.
