"Singam 3" went through several changes of release date, before being released on 9 February 2017 coinciding with Thaipusam festival. The film was completed in mid-2016 and the team completed post-production work aiming to have a theatrical release in October to coincide either with the Ayudha Puja or Diwali season, but the release was postponed to avoid a box office clash with Suriya's brother, Karthi's film, "Kaashmora". The film was then scheduled to release on 16 December. However, due to a request from the makers of "Dhruva", the film release date was pushed even later on 23 December to make most of the Christmas holiday season, but was delayed after the team chose to allow the public of Tamil Nadu more time to recuperate from the aftermath of Cyclone Vardah, the death of Chief Minister J. Jayalalithaa and the demonetisation problems. Prior to the film's revised release date of 26 January, PETA India had remarked that Suriya was trying to garner publicity for "Si3" by speaking out against the organisation at the 2017 pro-jallikattu protests. Suriya subsequently filed a legal notice against PETA for the defamatory allegations. The film was pushed back even further following riots in Chennai at the end of the protest, with the producers finalising a worldwide theatrical release date of 9 February. In Malaysia, this movie was available in Astro First channel 481 in early April 2017. Viewers need to pay RM15.00 to watch the movie for two days.
