Dhadak (transl. Heartbeat) is a 2018 Indian Hindi-language romance film written and directed by Shashank Khaitan and jointly produced by Karan Johar, Hiroo Yash Johar and Apoorva Mehta under the Dharma Productions banner with Zee Studios as a sponsor producer. A remake of the 2016 Marathi language film Sairat by Nagraj Manjule, also produced by Zee Studios, the film stars Ishaan Khatter and debutant Janhvi Kapoor, with Ashutosh Rana, Ankit Bisht, Shridhar Watsar, Kshitij Kumar and Aishwarya Narkar in supporting roles.

Johar had announced the production of Dhadak in November 2017 which marked the screen debut of Janhvi Kapoor, daughter of Sridevi and Boney Kapoor. Principal photography commenced in December 2017 and was completed in April 2018. The film's soundtrack was composed by Ajay–Atul with lyrics by Amitabh Bhattacharya and background score composed by John Stewart Eduri. The film was distributed internationally by Zee Studios.

Dhadak, which was originally scheduled to release on 6 July 2018, was postponed and had its worldwide theatrical release on 20 July 2018. It received negative reviews from film critics for glossing over the subject of caste-based discrimination, which was present in Sairat, and for being a poor remake of the original, although Khatter's performance was praised. However, Dhadak emerged as a commercial success, grossing over ₹110.11 crore (US$13 million) worldwide.

A sequel, which will remake Pariyerum Perumal (2018), starring Siddhant Chaturvedi and Triptii Dimri titled Dhadak 2 is set to be released in 2024.
