Meg Giry is one of the fictional characters from Gaston Leroux's novel The Phantom of the Opera. In the story she is Madame Giry's oldest daughter.
In the novel she is described as having “eyes black as sloes, hair black as ink, a swarthy complexion and a poor little skin stretched over poor little bones". She is also, in the novel, portrayed as a child of around fifteen years old and adores having her own way and attention. Due to her mother's role as the keeper of Box Five, Meg occasionally acts as a source of information about the ghost to the other ballet girls. She is described by the author in the prologue as "the most charming star of our admirable corps de ballet."
In the Andrew Lloyd Webber adaptation, she is older and her personality is much sweeter, caring and innocent showing genuine concern for Christine's claim of an Angel of Music (really the Phantom) coaching her. Meg is more curvaceous and has blonde hair and blue eyes.
Madame Giry is compelled to work for the Phantom because he left her a letter that told her that Meg (should she deserve it) would become Empress. Early in the novel, it is explained in the Prologue that Meg Giry, after the story's events, had indeed become the Baroness de Barbazac.
Giry is a commune in the Nièvre department in central France.
At the 1999 census, the population was 196. On 1 January 2006, the estimate was 215.
