Dil Dhadakne Do (transl. 'Let the heart beat') is a 2015 Indian Hindi-language family comedy drama film directed by Zoya Akhtar and produced by Ritesh Sidhwani and Farhan Akhtar under the Excel Entertainment banner. The film has an ensemble cast of Anil Kapoor, Shefali Shah, Farhan Akhtar, Priyanka Chopra, Ranveer Singh and Anushka Sharma with a voice-over narration by Aamir Khan. The supporting cast includes Rahul Bose, Zarina Wahab, Vikrant Massey, Pawan Chopra, Parmeet Sethi, Dolly Mattdo and Manoj Pahwa. The film tells the story of the Mehras, a dysfunctional family who invite their family and friends on a 10-day cruise trip to celebrate the parents' 30th wedding anniversary and later reconcile.

Zoya conceived the film as a family drama centred on a brother-sister relationship. She wanted to depict a more realistic sibling relationship in contrast to the dubious and over-the-top portrayal for which Bollywood is known. She later wrote the script with her friend and longtime collaborator Reema Kagti, while Farhan penned the dialogues. Much of the principal photography was done on Pullmantur Cruises' ship MS Sovereign while sailing across the Mediterranean and Europe, and on land in France, Spain, Italy, Tunisia, and Turkey.

The soundtrack was composed by the trio Shankar–Ehsaan–Loy, with lyrics by Javed Akhtar. The film was released worldwide on 5 June 2015 to positive reviews from critics, who praised the performances of Kapoor, Shah, Chopra, and Singh, as well as Akhtar's direction, the film's music, cinematography and costumes; however, it received criticism for its long runtime and climax. Nevertheless, it proved to be a commercial success, having grossed ₹1.44 billion (equivalent to ₹2.2 billion or US$25 million in 2023) on a budget of ₹550 million (equivalent to ₹830 million or US$9.6 million in 2023).

At the 61st Filmfare Awards, Dil Dhadakne Do received 5 nominations, including Best Supporting Actress (for both Shah and Sharma), winning Best Supporting Actor (Kapoor). It also received 9 nominations at the 2016 Screen Awards, including Best Film and Best Director (Zoya Akhtar), and won 2 awards – Best Supporting Actor (Kapoor) and Best Ensemble Cast.
