Tees Maar Khan (transl.  He Who Killed Thirty) is a 2010 Indian Hindi-language heist comedy film directed by Farah Khan and produced by Twinkle Khanna, editor Shirish Kunder and Ronnie Screwvala under UTV Motion Pictures, Hari Om Entertainment, and Three's Company. A remake of the 1966 Italian film After the Fox, whose story was adapted by Shirish and scripted by him and his brother Ashmith Kunder, the film stars Akshay Kumar, Akshaye Khanna, and Katrina Kaif in lead roles. Salman Khan and Anil Kapoor make special appearances.

Tees Maar Khan was released worldwide on 24 December 2010, on Christmas Eve. The film was a moderate commercial success at the box office, and is today primarily remembered for Kaif's dance number "Sheila Ki Jawani". The theatrical trailer and title song of the film were released on UTV Motion Pictures' YouTube channel on 4 August 2010 for promotional purposes. The trailer premiered in theatres with Vipul Amrutlal Shah's romantic comedy Action Replayy, also starring Kumar, and Rohit Shetty's action comedy Golmaal 3 on 5 November 2010. Featuring music composed by Vishal-Shekhar, with Shirish composing the background score and the title track while also writing it, the film was Khan's only film till date to neither be written by her nor feature her frequent collaborator Shah Rukh Khan.

Despite having received negative reviews upon release, Tees Maar Khan has achieved cult status as a classic parody in filmmaking.
