Rajadhi Raja is a 2009 Indian Tamil language vigilante action film written and directed by Sakthi Chidambaram.
The film stars Raghava Lawrence, Mumtaj, Snigdha Akolkar, Kamna Jethmalani, Meenakshi, and Karunas.
Tragedy strikes the life of Raja, a native of Coutrallam, when his father loses his hand in an operation by a drunk doctor. The doctor bribes local police to cover up the incident, leading to his father's death. On his deathbed, Raja's father makes him promise to turn his three brothers into a police officer, a lawyer, and a doctor.
Raja fulfills his promise by stopping his studies to earn money for his brothers' education and training. They are provided shelter and food by a local elderly woman, whom Raja affectionately calls Paatti.
