Koduri Srisaila Sri Rajamouli (এস. এস. রাজামৌলি) is an Indian filmmaker who works in Telugu cinema. Known for his epic, action and fantasy genre films, he is the highest grossing Indian director of all time, as well as the highest-paid director in Indian cinema. Rajamouli is a recipient of various national and international honours including a New York Film Critics Circle award, a Critics' Choice Movie Award, two Saturn Awards, four National Film Awards, and five Filmfare Awards. In 2016, the Government of India honoured him with the Padma Shri, for his contributions in the field of art. In 2023, he was included on the Time's list of the 100 most influential people in the world.

Rajamouli has been described by film trade analyst Komal Nahta as "the biggest Indian film director ever" and by SOAS professor Rachel Dwyer as "India's most significant director today". He has directed twelve feature films, all of which have been box office successes. Three of his films—Baahubali: The Beginning (2015), Baahubali 2: The Conclusion (2017), and RRR (2022)—rank among the top 15 highest grossing-films in India. Each of these films was the most expensive Indian production at the time of its release. Baahubali 2 became the first Indian film to gross over ₹1,000 crore and held the record as the highest-grossing Indian film. It also sold over 100 million tickets, the highest for any film in India since Sholay (1975).

Rajamouli married Rama, sister-in-law of his cousin Keeravani in 2001. After their marriage, Rama worked as a costume designer for many of Rajamouli's films. He adopted Karthikeya, Rama's son from her previous marriage. The couple also has an adopted daughter Mayookha. Karthikeya is married to Pooja Prasad, niece of Telugu actor Jagapathi Babu.

Rajamouli's cousin, M. M. Keeravani has worked as the music composer for all of his films. His other cousins Kalyani Malik and M. M. Srilekha are also music composers. S. S. Kanchi, a screenwriter and actor known for his role in the sitcom Amrutham is also one of his cousins. He collaborated with Rajamouli as a script doctor on many of his films and also acted in four of his films. Raja Koduri, an Executive vice-president at Intel is also a cousin of his. Rajamouli considers K. Raghavendra Rao as his guru and mentor. He called Gunnam Gangaraju his philosopher and guide who made an impact on his worldview.

Rajamouli is nicknamed Jakkanna after the legendary c.12th century sculptor Jakanachari (known in Telugu as Jakkanna) who is credited with building numerous temples during the Hoysala reign. The moniker was coined by actor Rajeev Kanakala during the making of the TV serial Santhi Nivasam (c. 2000) directed by Rajamouli and was in reference to his work ethic and perfectionism like the famed sculptor.

A self confessed "film freak", Rajamouli's penchant for filmmaking is best captured by the word "emotion". He often stated that his films are based on stories driven by human emotions. Revenge is a recurring theme in his films. Several of Rajamouli's films feature flashback episodes where the protagonist's backstory is revealed, typically in the second half of the film. This narrative style is used in Simhadri, Vikramarkudu, Magadheera, Baahubali: The Beginning, and RRR.

Describing his films as “big-scale action movies driven by hard-core emotion”, Rajamouli considers himself to be a magnifying glass that enhances the various emotions of the characters on screen, and sees the presence of violent action as an integral factor that engages the viewer with on screen proceedings. "For me, the character being emotionally charged up at that moment to go into that action sequence is very, very important," said Rajamouli about action sequences in his films.
