Vivekanathan (Tamil : விவேக்) is a Tamil film comedian from India. In contrast to other comedians in Tamil cinema, Vivek is more of a satirist than a slapstick comedian. His movies draw humor from scenes of daily life in Tamil Nadu (especially Chennai) and the surrounding regions.

Vivek ( िववेक in Devanagari script) is an Indian name that refers to a person's ability to "discriminate". For example, to discern between right and wrong.
