Kurumbu (transl. Naughty) is a 2003 Indian Tamil-language romantic comedy film directed by Vishnuvardhan, making his directorial debut. The film, a remake of the 2002 Telugu film Allari, stars Naresh, who also starred in the original version, which marked his acting debut, along with Nikita Thukral and Diya. The film released on 21 November 2003 to poor reviews, failing to repeat the success of the original version and hence, ending up as a box-office bomb, being considered as the only commercially unsuccessful film of director Vishnuvardhan. Although there is the Telugu original, it was dubbed in Telugu also as Naa Allari.

It deals with a love triangle between three teenagers. The story portrays how the hero finds his true love.
