The Winter's Bone star has been cast as Katniss Everdeen in the film, according to movie news website TheWrap.com.
Lawrence reportedly beat fellow 2011 Oscar nominee Hailee Steinfeld to the role in the saga of battling teenagers.
The film will be directed by Gary Ross, and is slated to hit cinemas in a year (Mar12).
Confirming the news of Lawrence's casting, Ross says, "I’m so excited to work with Jen and see her bring this character to life. Katniss requires a young actress with strength, depth, complexity, tenderness, and power. There are very few people alive who can bring that to a role. Jen brings it in spades. She’s going to be an amazing Katniss."
