Parasakthi (transl. The Supreme Power) is an upcoming Indian Tamil-language political period drama film directed by Sudha Kongara and produced by Dawn Pictures. The film stars Sivakarthikeyan, Ravi Mohan, Atharvaa and Sreeleela (in her Tamil debut) in the lead roles, alongside Dev Ramnath, Prithvi Rajan, Guru Somasundaram, Basil Joseph and Ranjan Ramanayake. Based on true events, the story revolves around the Anti-Hindi agitations in Tamil Nadu that happened in 1965.

Initially, Sudha and Suriya were set to collaborate after Soorarai Pottru (2020). Announced in October 2023, Dulquer Salmaan, Nazriya Nazim and Vijay Varma were on board in the lead roles, tentatively titled Suriya 43. Due to unknown reasons, however, the film was shelved. Sudha then revived the script with Sivakarthikeyan replacing Suriya. The film was announced in December 2024 under the tentative title SK25, as it is the actor's 25th film as a lead actor, and the official title was announced the following month. Principal photography commenced the same month and has currently been taking place at Chennai, Chidambaram, Karaikudi, Madurai and Colombo. The film has music composed by G. V. Prakash Kumar, cinematography handled by Ravi K. Chandran and editing by Sathish Suriya.

Parasakthi is scheduled to be released in January 2026, coinciding with Pongal.
