The British expedition to Tibet, also known as the British invasion of Tibet or the Younghusband expedition to Tibet began in December 1903 and lasted until September 1904. The expedition was effectively a temporary invasion by British Indian forces under the auspices of the Tibet Frontier Commission, whose purported mission was to establish diplomatic relations and resolve the dispute over the border between Tibet and Sikkim. In the nineteenth century, the British conquered Burma and Sikkim, occupying the whole southern flank of Tibet. The Tibetan Ganden Phodrang regime, which was then under administrative rule of the Qing dynasty, remained the only Himalayan state free of British influence.

The expedition was intended to counter Russia's perceived ambitions in the East and was initiated largely by Lord Curzon, the head of the British India government. Curzon had long obsessed over Russia's advance into Central Asia and now feared a Russian invasion of British India. In April 1903, the British received clear assurances from the Russian government that it had no interest in Tibet. "In spite, however, of the Russian assurances, Lord Curzon continued to press for the dispatch of a mission to Tibet", a high level British political officer noted.
