Zinda (English: Alive) is a 2006 Indian Hindi-language action film written and directed by Sanjay Gupta, who co-wrote the film with Suresh Nair. It stars Sanjay Dutt, John Abraham, Lara Dutta and Celina Jaitly. Vishal–Shekhar composed the film's thematic music, while the background score was composed by Sanjoy Chowdhury. Dutt suggested the script to Gupta post the release of their previous film Musafir, following which the film went into production. Set in Thailand, the plot centers on Balajeet "Bala" Roy, who gets kidnapped and held hostage in a cell. After getting released without any explanation, Bala sets out to find his captor and the reason behind his captivity.

Zinda was released on 13 January 2006, and has been identified as an unauthorized adaptation of the South Korean film Oldboy, which itself is an official adaptation of the Japanese manga of the same name. Show East, the producers of Oldboy, who had already sold the remake rights to DreamWorks in 2004 had initially expressed legal concerns, but no legal action was taken as the studio had shut down. The film was a box-office flop, grossing ₹17.6 crore worldwide against a budget of ₹13 crore.
