Krishnamoorthy (1963/1964 - 7 October 2019) was a comedian in the Tamil film industry in India.
Krishnamoorthy moved from his home town Tiruvannamalai to Madras in 1983 hoping to become an actor in films. Despite being initially unsuccessful, he joined the crew of the film Kuzhandhai Yesu (1984) as an office boy, and by the end of production, he was assigned the role of production manager. He subsequently went on to work on several films and adverts as a member of the crew. As a result, he was initially credited in films as Manager Krishnamoorthy.
Krishnamoorthy made a breakthrough as a comedy actor through his role in Thavasi (2001), where he notably appeared in a scene where his character asks Vadivelu's character for directions to meet terrorist Osama Bin Laden. He subsequently worked on several films in the 2000s as a comedian, often appearing in scenes alongside Vadivelu.
He later won critical acclaim for his portrayal of Murugan, a middle manager in a human trafficking group in Bala's Naan Kadavul (2009) and as a corrupt police constable in Mouna Guru (2011).
He died in the early morning of 7 October 2019 of a heart attack in Kumily in Kerala, where he was shooting for the film Pei Mama directed by Sakthi Chidambaram. He was survived by his wife and two children.
