Princess Protection Program is a 2009 Disney Channel Original Movie that premiered on June 26, 2009 in the United States and winner of the Teen Choice Awards 2009 for Choice Summer TV Show. It stars Demi Lovato and Selena Gomez.

Princess Rosalinda Maria Montoya Fiore (Demi Lovato) is about to be crowned queen of the small nation of Costa Luna. General Kane (Johnny Ray Rodriguez), the dictator of neighbouring country Costa Estrella, invades her palace with his agents during her coronation rehearsal, and attempts to capture the royal family and take over the country. Joe Mason (Tom Verica), an agent of the Princess Protection Program, a secret organization funded by royal families that looks after endangered princesses, whisks her away to safety via helicopter. Kane’s agents however succeed in capturing her mother, Queen Sophia.

The Princess Protection Program hides Rosalinda in Mr. Mason’s home in Louisiana, where she is to pretend to be a typical American teenager named Rosie Gonzalez. She meets Mr. Mason's daughter, Carter Mason (Selena Gomez), an insecure tomboy who works at the family bait shop and dreams of going to the homecoming dance with her crush, Donny (Robert Adamson). Though Carter initially treats Rosie with annoyance and barely-masked hostility, she warms up to her after Rosie explains her situation, and the two become close friends. Carter teaches Rosalinda to act like a normal girl and Rosie shows Carter how to disarm those that scorn them by behaving as a princess. Rosie soon becomes popular at their high school.
