Fatehgarh Sahib is a city and a sacred pilgrimage site of Sikhism in the north west Indian state of Punjab. It is the headquarters of Fatehgarh Sahib district, located about 5 kilometres (3.1 mi) north of Sirhind. Fatehgarh Sahib is named after Fateh Singh, the 7-year-old son of Guru Gobind Singh, who was seized and buried alive, along with his 9-year-old brother Zoravar Singh, by the Mughals under the orders of governor Wazir Khan during the ongoing Mughal-Sikh wars of the early 18th century. The town experienced major historical events after the martyrdom of the sons in 1705, with frequent changes of control between the Sikhs and Mughals.

Fatehgarh Sahib district is one of the twenty-three districts of the state of Punjab, India, with its headquarters in the town of Fatehgarh Sahib.
