Dharala Prabhu (transl. Generous Lord) is a 2020 Indian Tamil-language romantic comedy film written and directed by Krishna Marimuthu in his directorial debut. A remake of the 2012 Hindi film Vicky Donor, the film stars Harish Kalyan, Tanya Hope and Vivek. The film's concept is set against the backdrop of sperm donation and infertility, with Prabhu (Harish Kalyan) approached by Dr. Kannadasan (Vivek), the owner of a fertility clinic, to become a sperm donor for which he eventually agrees.

The film was initially reported for a Tamil remake in early 2012, with a project starring Siddharth in the lead role eventually fails to materialise despite its announcements. Eight years later in May 2019, Screen Scene Media Entertainment acquired the remake rights with Harish Kalyan being hired for the film and the project started the following month. The cinematography was handled by Selvakumar S. K. and edited by Kripakaran, the film features a soundtrack album composed by Anirudh Ravichander, Sean Roldan, Vivek-Mervin, Inno Genga, Madley Blues, Bharath Shankar, Kaber Vasuki and Oorka.

Dharala Prabhu was released theatrically on 13 March 2020. With theatres being shut down due to the COVID-19 pandemic, affecting its collections, the film was made available in digital platform Amazon Prime Video, less than a month after its release. Nevertheless, the film opened to positive reviews from critics and became a breakthrough film for Harish Kalyan and ended up as a decent hit by its other revenue. The film also marked Vivek's final release before his death.
