Vinnaithaandi Varuvaayaa (transl. Will you cross the skies for me?) is a 2010 Indian Tamil-language musical romantic drama film written and directed by Gautham Vasudev Menon, starring Silambarasan and Trisha. Jointly produced by Elred Kumar, Jayaraman, VTV Ganesh and P. Madan under the banner Escape Artists Motion Pictures and RS Infotainment, the film was distributed by Udhayanidhi Stalin's Red Giant Movies. The story was simultaneously shot in Telugu as Ye Maaya Chesave, starring Naga Chaitanya and Samantha.

Launched after a wave of publicity posters with no details about the cast and crew, Vinnaithaandi Varuvaayaa began its first schedule of filming in February 2009. Shooting continued through 2009, with the film garnering significant media interest, with schedules in Malta and the United States. Before release, it became the first Tamil project to have a music soundtrack premiere outside of India, with a successful launch at the British Academy of Film and Television Arts (BAFTAs) in London. The film features soundtrack composed by A. R. Rahman, cinematography by Manoj Paramahamsa and editing by Anthony Gonsalves.

Vinnaithaandi Varuvaayaa explores the complicated relationship between a Hindu Tamil boy, Karthik Sivakumar, and a Malayali Christian girl, Jessie from Alappuzha, Kerala. Karthik falls in love with Jessie only to be met by her indifference and reluctance as they belong to different religions and her strict conservative family will never consent to their union. The film released on 26 February 2010, along with the Telugu version to advance bookings worldwide. It was later remade in Hindi as Ekk Deewana Tha. A short film/sequel titled Karthik Dial Seytha Yenn, again directed by Menon with Silambarasan and Trisha reprising their roles, was released in May 2020.
