Hadleigh is a British television series that was produced by Yorkshire Television and originally ran from 1969 to 1976. Developed by Robert Barr, it was a sequel to the writer's earlier Gazette (1968) for the same company. The theme music was composed by Alan Moorhouse and, from series 3, Tony Hatch.

James Hadleigh, played by Gerald Harper, was "the perfect squire, paternalistically careful of his tenantry's welfare, beloved in the village, respected in the council." A "knight in a shining white Aston Martin V8 (actually a Monteverdi 375L), he sets about correcting local injustices". His wife, from a suburban middle-class background, was played by Hilary Dwyer. The series attracted around 17 million viewers at its peak.
