The Colvin family, for the purposes of this article, is that group of people descended from James Colquhoun Colvin (1767–1847), the son of Alexander Colvin (1718–1791) and Elizabeth 'Bettie' née Kennedy (1714–1795). James was a merchant trading between London and Calcutta during the East India Company. This Anglo-Indian family was intimately involved with the British Raj, first as traders and then as administrators and soldiers. Their descendants continued in service to the British Empire and later in some of its constituent countries.

John Russell Colvin was a British administrator of the East India Company, and Lieutenant-Governor of the North-Western Provinces from 1853 until his death from cholera during the Indian Rebellion of 1857.
