Chak De! India (transl. Let's go! India – transl. Go! India) is a 2007 Indian Hindi-language sports drama film directed by Shimit Amin and produced by Aditya Chopra under the banner of Yash Raj Films. The film stars Shah Rukh Khan as Kabir Khan, the former captain of the India men's national field hockey team. After a disastrous loss to Pakistan, Khan is ostracized from the sport owing to religious prejudice. 7 years later in an attempt to redeem himself, he becomes the coach of the India women's national field hockey team, with the goal of turning its 16 contentious players into an award-winning team.

Jaideep Sahni, a screenwriter, was inspired by the women's national field hockey team's win at the 2002 Commonwealth Games to develop Chak De! India's script after reading about it in a newspaper. The screenplay was fictional and the characters, while inspired by the real team and coaches, were invented by Sahni. Kabir Khan's struggles bore resemblance to those faced by real-life hockey player Mir Ranjan Negi, although Sahni was unaware of Negi's tribulations while writing the script. On the suggestion of Maharaj Krishan Kaushik, then coach of the women's hockey team, Sahni invited Negi to join the film's production team. A combination of professional players and actors were cast as the sixteen team members; workshops were conducted for training the actors in hockey and the players in acting. Kaushik and Negi would train Sahni, Khan and the other cast members over a period of six months. The sports scenes were choreographed by Rob Miller, and the soundtrack was composed by Salim–Sulaiman, with lyrics written by Sahni.

Chak De! India was released worldwide on 10 August 2007, coinciding with the country's 60th Independence Day, and grossed ₹109 crore (US$26.36 million) on a ₹20 crore (US$4.84 million) budget, thus becoming the third-highest grossing Hindi film of 2007. It received widespread critical acclaim upon release, with praise for its direction, story, screenplay, dialogues, feminist themes, and performances of the cast, with high praise directed towards Khan's performance. A recipient of numerous accolades, Chak De! India won the National Film Award for Best Popular Film Providing Wholesome Entertainment at the 55th National Film Awards. It received a leading 10 nominations at the 53rd Filmfare Awards, including Best Film, Best Director (Amin) and Best Supporting Actress (Shukla), and won a leading 5 awards, including Best Film (Critics) and Best Actor (Khan).

The title track song "Chak De! India," now doubles as a sports anthem in India.

Chak De! India opens in Delhi during the final minutes of a Hockey World Cup match between Pakistan and India, with Pakistan leading 1–0. When Indian team captain Kabir Khan is fouled, he takes a penalty stroke. His shot just misses, causing India to lose the match. Soon afterwards, media outlets circulate a photograph of Khan shaking hands and embracing the Pakistani captain. The sporting gesture is misunderstood, and Khan is suspected of throwing the game out of sympathy towards Pakistan. Religious prejudice forces him and his mother to leave town.

Seven years later Mr. Tripathi, the head of India's hockey association, meets with field hockey advocate Uttam Singh to discuss the Indian women's hockey team. According to Tripathi, the team has no future since the only long-term role for women is to "cook and clean". Uttam, however, tells him that Khan wants to coach the team. Initially skeptical, Tripathi agrees to the arrangement.

Khan finds himself in charge of a group of 16 young women divided by their fiercely competitive natures and regional prejudices. Komal Chautala, a village girl from Haryana, clashes with Preeti Sabarwal from Chandigarh; short-tempered Balbir Kaur from Punjab bullies Rani Dispotta and Soimoi Kerketa, who are from remote villages in Jharkhand. Mary Ralte from Mizoram and Molly Zimik from Manipur in Northeast India face widespread racial discrimination and even sexual harassment from some strangers. Team Captain Vidya Sharma must choose between hockey and the wishes of her husband Rakesh's family, and Preeti's fiancé—Abhimanyu Singh, Vice-Captain of the India national cricket team— brushes off hockey as unimportant to their future as a couple.

Khan realises that he can make the girls winners only if he can help them overcome their differences. During his first few days as coach, he benches several players who refuse to follow his rules—including Bindiya Naik, the most experienced player. In response, Bindiya repeatedly encourages the other players to defy Khan. When she finally succeeds, Khan angrily resigns; however, he invites the staff and team to a farewell lunch at McDonald's. During the lunch, local boys eve tease Mary; Balbir attacks them, triggering a brawl between the boys and the team. Khan, recognising that they are finally acting as one for the first time, prevents the staff from intervening; he only stops a man from hitting one of the women from behind with a cricket bat. After the fight, the women realise Khan's intentions and ask him to remain their coach.
