Mallory Grace is the main heroine of The Spiderwick Chronicles.

The Spiderwick Chronicles

Mallory Grace is Jared and Simon's thirteen-year-old sister. She is a very skilled fencer and sometimes uses her brothers for practice. Mallory may be rude, sarcastic, and stubborn, but she really cares for her two brothers and believes in Jared when he discovers Arthur Spiderwick's field guide and the fantastical creatures that surround them. 


  • Mallory is played by Sarah Bolger in the film adaptation.
  • She is the quintessential big sister - arguing with her siblings but still caring about them.
