Si3 (also known as Singam 3) is an upcoming 2017 Indian Tamil-language action-masala film written and directed by Hari. A sequel to Singam II (2013) and the third film in the Singam franchise, it stars Suriya, Anushka Shetty and Shruti Haasan in the lead roles.

Principal photography commenced in January 2016 in Visakhapatnam, Andhra Pradesh. The film is scheduled for a worldwide release along with the Telugu dubbed version, Yamudu 3.

Following the commercial success of Singam 2, Hari was keen to collaborate with Suriya for another action film with a fresh script away from the Singam franchise, and agreed terms in principle with the actor in October 2014. Hari revealed that as a result of pressure from those around him, he later developed the one-line story from the film into a script for a third part of Singam. While the first film was primarily shot within Tamil Nadu and the second featured a few scenes in South Africa, Hari stated that the third part would be more "international" and would be set in three countries as the protagonist tackles a global issue.

While most of the cast was retained from the earlier films, Shruti Haasan was added to the team in July 2015 to portray another leading female role, while Anirudh Ravichander was signed as the music composer replacing Devi Sri Prasad. Anirudh later opted out of the project citing scheduling issues and Harris Jayaraj was brought in to compose the film's music.Vivek, who portrayed the police officer Erimalai in the first two films, declined to reprise his role in this film as he felt he "did not have a meaty role in it". New actors to the series including Radhika, Soori, Robo Shankar, Krish and Nithin Sathya were added to the cast, while Thakur Anoop Singh was signed on to portray the lead antagonist.
