Thangappathakkam (transl. Gold medal) is a 1974 Indian Tamil-language drama film, directed by P. Madhavan and written by Mahendran. Based on Mahendran's play of the same name, the film stars Sivaji Ganesan, K. R. Vijaya, Srikanth and Prameela. It focuses on a disciplined Superintendent of Police who is dedicated to his job, while his son, on the contrary, is rebellious by nature and grows to resent his father. Ganesan reprises his role from the play.

Thangappathakkam was released on 1 June 1974. The film was a commercial success, running for over 175 days in theatres, and thereby becoming a silver jubilee film. It served as an inspiration for the Telugu film Kondaveeti Simham (1981), the Kannada film Kadamba (2004) and the Hindi film Shakti (1982).
