Sir Anthony Carlisle FRCS, FRS (15 February 1768 in Stillington, County Durham, England – 2 November 1840 in London) was an English surgeon.

He was apprenticed to medical practitioners in York and Durham, including his uncle Anthony Hubback and William Green.

[2] In 1800, he and William Nicholson discovered electrolysis by passing a voltaic current through water, decomposing it into its constituent elements of hydrogen and oxygen.

He was Surgeon Extraordinary (1820–1830) to King George IV, by whom he was knighted on 24 July 1821.

It is possible that he may have been the author of The Horrors of Oakendale Abbey, a gothic novel published anonymously in 1797 and attributed to a "Mrs Carver".
