The Ghadr (or Ghadar) movement was a revolutionary movement that aimed to overthrow British colonial rule in India during the early 20th century. It was launched by Indian immigrants, mainly Sikhs and Hindus, residing in North America, particularly in the United States and Canada.

The Ghadr Party was formed in 1913 in San Francisco, California, to liberate India from British rule through an armed revolution.

Prominent leaders of the Ghadr movement included Lala Har Dayal, Sohan Singh Bhakna, Kartar Singh Sarabha, and Vishnu Ganesh Pingle.
