George Hadfield (28 December 1787 – 21 April 1879) was an English lawyer, author and Radical politician who represented Sheffield for 22 years.
He spent many years in litigation and controversy in connection with the alienation of Lady Hewley's and other charities.
The dispute was finally resolved by the passing of the Dissenters' Chapels Act 1844 which he had played a part in framing.
With Thomas Raffles and William Roby he established the Lancashire Independent College, first at Blackburn and then at Whalley Range, where in 1840 he laid the foundation-stone of the new building and gave £2,000 towards the cost of the erection.
He spoke frequently in the House of Commons, and his advice on matters relating to legal reform was much appreciated.
