Vettai (transl. Hunt) is a 2012 Indian Tamil-language action comedy film co-produced, written and directed by N. Linguswamy. The film stars Arya and R. Madhavan in the lead roles, while Sameera Reddy, Amala Paul, Ashutosh Rana, Nassar and Thambi Ramaiah appear in supporting roles. The music was composed by Yuvan Shankar Raja, and cinematography and editing handled by Nirav Shah and Anthony.

The film was announced shortly after the release of Lingusamy's Paiyaa, with Dhayanidhi Alagiri's Cloud Nine Movies agreeing to produce the film, following a successful collaboration during the director's previous film. During a lengthy pre-production phase, the film underwent changes in its main cast and Cloud Nine Movies pulled out of the project. Linguswamy's own banner Thirupathi Brothers takes up the film. Filming was initially planned to begin by mid-2010, but was delayed until March 2011.

Vettai was released on 14 January 2012, coinciding with Pongal festival, and became a commercial success at the box office. The film was remade in Telugu as Tadakha (2013), in Bengali as Hitman (2014) and in Hindi as Baaghi 3 (2020).
