John FitzGibbon, 1st Earl of Clare PC (Ire) was Attorney-General for Ireland from 1783 to 1789 and Lord Chancellor of Ireland from 1789 to 1802.

The Attorney-General for Ireland was an Irish and then United Kingdom government office-holder. He was senior in rank to the Solicitor-General for Ireland: both advised the Crown on Irish legal matters. With the establishment of the Irish Free State in 1922, the duties of the Attorney-General and Solicitor-General for Ireland were taken over by the Attorney General of Ireland. The office of Solicitor-General for Ireland was abolished at the same time for reasons of economy. This led to repeated complaints from the first Attorney General of Ireland, Hugh Kennedy, about the "immense volume of work" which he was now forced to deal with single-handedly.
