Goa is a 2010 Indian Tamil-language romantic comedy film written by Sampath Ravi and directed by Venkat Prabhu in his third directorial project. Starring his regular cast consisting of Jai, Vaibhav, and Premji along with Aravind Akash, Sampath Raj, Piaa Bajpai, Sneha, and the debutant Australian model Melanie Marie in other roles, the film is the first production of Soundarya Rajinikanth's Ocher Picture Productions. Actors Silambarasan Rajendar, Nayantara and Prasanna make guest appearances in the film, which features music composed by Yuvan Shankar Raja, whilst cinematography is handled by Sakthi Saravanan and the film is edited by K. L. Praveen and N. B. Srikanth.

The film follows the journey of three young men, Vinayagam, Ramarajan and Saamikannu, who flee from their remote, conservative village to escape their overly strict families and travel to the international tourist-destination Goa, after encountering a friend who had fallen in love with a Caucasian girl whilst on holiday there. The film explores their time in Goa, the people they meet ranging from gay hoteliers to suave casino owners, and dwells on the relationships they encounter in the region.

The film, which began pre-production work in August 2008, became highly anticipated before release due to the successes of the director's prior two films Chennai 600028 and Saroja. Filming began in April 2009 and took place in various locations: in the title location of Goa as well as in Pannapuram, Tamil Nadu and Langkawi, Malaysia with the latter being used due to the monsoonal season of Goa, forcing the team to relocate. Before release, the film was given an adult rating by the Central Board of Film Certification, despite much contention from the team with the film also avoiding a court case in regard to the producer's loan. The film released on 29 January 2010 to mostly positive reviews. The film was remade in Kannada language using the same title and released in 2015.
