Kadhalan (Tamil pronunciation: [kaːt̪ɐlɐn] transl. Loverboy) is a 1994 Indian Tamil-language romantic thriller film directed by S. Shankar and produced by K. T. Kunjumon, who co-wrote the story. The film stars Prabhu Deva and Nagma (in her debut in Tamil cinema), alongside Vadivelu, Raghuvaran, Girish Karnad and S. P. Balasubrahmanyam. In the film, a college student falls in love with the daughter of the state's governor, who has plans of toppling the state government.

Kunjumon decided to collaborate with Shankar for the second time after the success of Gentleman (1993) and the story Shankar developed was that of a romance between an ordinary man and a wealthy girl; to increase the scale of the project, Kunjumon incorporated the cold-war between the then chief minister of Tamil Nadu J. Jayalalithaa and governor Marri Chenna Reddy into the script. The dialogues were written by Balakumaran, while the music was composed by A. R. Rahman. The cinematography was handled by Jeeva and editing by B. Lenin and V. T. Vijayan.

Kadhalan was released on 17 September 1994 and became a major commercial success. The film earned several accolades, including two Filmfare Awards South and four National Film Awards.
