Suriya 45 is the working title of an upcoming Indian Tamil-language film directed by RJ Balaji, who co-wrote the script with Rathna Kumar, and produced by Dream Warrior Pictures.

The film stars Suriya and Trisha Krishnan, with Swasika, Indrans, Yogi Babu, Sshivada, Natty Subramaniam and Supreeth Reddy in supporting roles.

Before the release of Kanguva in late 2024, it was reported that RJ Balaji had met Suriya and narrated a script which impressed the actor.
