John FitzGibbon, 2nd Earl of Clare KP GCH PC (10 July 1792 – 18 August 1851) was an Anglo Irish aristocrat and politician.

[1] The couple lived apart, Lady Clare moving to the Isle of Wight where she built a Catholic church at Ryde and a Priory at Carisbrooke.

Byron had claimed to love him "ad infinitum" and said that he could never hear the word "Clare" without "a murmur of the heart".

[4] Lord Clare died on 18 August 1851 and, as he had no issue, was succeeded in his titles and estates by his younger brother.

His widow was buried at Mountjoy Cemetery in Carisbrooke, Isle of Wight, next to her close companion Miss Charlotte Elliot.
