Lagaan (Hindi: लगान; English: Land Tax) is a 2001 Bollywood sports film written and directed by Ashutosh Gowariker. Aamir Khan, who was also the producer for the film, stars with Gracy Singh in the lead roles; British actors Rachel Shelley and Paul Blackthorne play the supporting roles. Made on a budget of 25 crore (US$4.99 million), the film was shot in an ancient village near Bhuj, India.

The film is set in the Victorian period of India's colonial British Raj and revolves around the peasants from a barren village who are oppressed by high taxes imposed by their rulers. They attempt to persuade the British officers to reduce the taxes because of poor agricultural produce. Instead, a wager is offered. If their village team beats a British team in a game of cricket, their taxes for three years would be cancelled. After accepting this wager, the villagers face the arduous task of learning an alien game and playing for a result that will change their village's destiny.

The film received critical acclaim and awards at various international film festivals, as well as many Indian film awards. It also became the third Hindi-language film to be nominated for the Academy Award for Best Foreign Language Film after Mother India (1957) and Salaam Bombay! (1988). It was one of the biggest box office hits of 2001. In 2010, the film was ranked #55 in Empire magazines "The 100 Best Films Of World Cinema". In 2011, the film was listed in Time Magazine's special "The All-TIME 25 Best Sports Movies".
