Kadhalan ( transl. Loverboy) is a 1994 Indian Tamil-language romantic thriller film written and directed by S. Shankar and produced by K. T. Kunjumon. The film stars Prabhu Deva and Nagma (in her major Tamil cinema debut), while Vadivelu, Raghuvaran, Girish Karnad, and S. P. Balasubrahmanyam play supporting roles. It focuses on a college student who falls in love with the state governor's daughter. The governor opposes this, and unknown to anyone, plans on 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 Tamil Nadu chief minister J. Jayalalithaa and the then governor Marri Chenna Reddy into the screenplay. The dialogues were written by Balakumaran, cinematography was handled by Jeeva, and editing by B. Lenin and V. T. Vijayan.

Kadhalan was released on 17 September 1994. The film was a major commercial success and won many recognitions and honours, including two South Filmfare Awards, and four National Film Awards.
