Adra Machan Visilu (Tamil: ஆட்ரா மச்சான் விசிலு, English: Dude, blow a whistle) is a 2016 Indian Tamil comedy film directed by Thiraivannan, starring Shiva, Srinivasan and Naina Sarwar in the lead roles.

The project was first reported in the media during June 2015, with reports stating that Powerstar Srinivasan would feature in a film titled Naanum Herodhaan which would tell the story of an actor forced to repay his fans for their losses during the film distribution process. The concept was considered to be a satire on the issue faced by Rajinikanth following the failure of Lingaa (2014) at the box office. The film began production during the final quarter of 2015 and the shoot progressed at the AVM Studios later under the tentative title of Simmakkal Sekhar.

The film opened in July 2016 to negative reviews. The critic from The Hindu stated "the filmmaking is shocking" and concluded that the film was "excruciating", while The New Indian Express stated "crude and loud with the message on your face, the film is clearly meant for the lowest denominator in the audience".

N. R. Raghunanthan composed the songs and background music for the film.
