Andhagan (transl. The Blind Man) is an upcoming Indian Tamil-language black comedy crime thriller film co-written and directed by Thiagarajan. A remake of the 2018 Hindi film Andhadhun, it stars Prashanth, Karthik, Simran, Priya Anand and Samuthirakani. The film revolves around a blind pianist who unwittingly becomes embroiled in a murder.

Thiagarajan purchased the remake rights of Andhadhun in 2019, and in January 2020 Mohan Raja was announced as director. Raja left the project that October, and was replaced by JJ Fredrick who also left months later, with Thiagarajan taking over directing. The film began production in March 2021, delayed from an April 2020 start date due to the COVID-19 pandemic, and was completed by November 2022. Despite that, it has faced repeated delays in its release.
