Andhagan: The Pianist (transl. Blind Man) is a 2024 Indian Tamil-language black comedy crime thriller film directed by Thiagarajan and produced by Staar Movies. The film stars Prashanth in the titular role, alongside Simran, Priya Anand, Karthik, Urvashi, Samuthirakani, Yogi Babu, K. S. Ravikumar, Vanitha Vijayakumar and Manobala. It is a remake of the 2018 Hindi-language film Andhadhun, and follows a blind pianist who unwittingly becomes embroiled in a murder.

In 2019, Thiagarajan purchased the remake rights of Andhadhun, which was followed by Mohan Raja being announced as director the following year. However, Raja left the project and was replaced with JJ Fredrick, who also left some months later, before Thiagarajan himself took over. Principal photography commenced in March 2021, and predominantly took place in Chennai before wrapping by November 2022. The film has music composed by Santhosh Narayanan, cinematography handled by Ravi Yadav and editing by Sathish Suriya.

Andhagan was released on 9 August 2024 in theatres, following production delays due to the COVID-19 pandemic. The film received generally positive reviews and became a commercial success. Some critics regarded it a comeback for Prashanth after a series of failures.
