A. Karunanidhi ( Tamil : கருணாநிதி) was an Indian actor and comedian who featured mainly in Tamil-language films.

Though he was a comedian, the roles he played in some of the films were so imperative to the story.

A case in point is his role in the award-winning film Veerapandiya Kattabomman.

In some of the films, he will not talk much, but his body language itself will make the audience laugh, as in Missiamma.

Apart from acting, at times he gave ideas for comedy scenes in films.
