Gunday (transl. Outlaws) is a 2014 Indian Hindi-language action thriller film written and directed by Ali Abbas Zafar and produced by Aditya Chopra. The film features Ranveer Singh, Arjun Kapoor, Priyanka Chopra and Irrfan Khan in the lead roles. Set in 1971–1988 Calcutta, Gunday is a story about two best friends and outlaws, who fall in love with a cabaret dancer, which causes rivalry and misunderstandings between them while a police officer tries to take advantage of this situation to eliminate them.

Zafar conceived the film as an amalgam of stories he had heard from his father as a child about the effects of war-caused immigration and the Mafia Raj's illegal marketing of coal. He wrote the film as a tale of the consequences of the struggle of two outlaws against the system, using his father's stories as a backdrop for the characters. Principal photography began in Mumbai in December 2012 before moving to Kolkata, where extensive filming was done. The soundtrack was produced by Sohail Sen, and the lyrics were penned by Irshad Kamil. It was the last Yash Raj Film narrated to Yash Chopra.

Gunday was released on 14 February 2014, receiving mixed to positive reviews from critics and was a commercial success, with a box-office gross of ₹23 million making it the 10th highest-grossing Bollywood release of 2014. The film won the Best Action at the 60th Filmfare Awards and was nominated for Best Choreography for the song "Tune Maari Entriyaan".
