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.

The Solicitor-General for Ireland was the holder of an Irish and then United Kingdom government office. The holder was a deputy to the Attorney-General for Ireland, and advised the Crown on Irish legal matters. On rare occasions, there was also a Deputy Attorney-General, who was distinct from the Solicitor-General. At least two holders of the office, Patrick Barnewall (1534–1550) and Sir Roger Wilbraham (1586–1603), played a leading role in Government, although in Barnewall's case, this may be partly because he, was also King's Serjeant. As with the Solicitor General for England and Wales, the Solicitor-General for Ireland was usually a barrister rather than a solicitor.
