The Chief Secretary for Ireland was a key political office in the British administration in Ireland. Nominally subordinate to the Lord Lieutenant, and officially the "Chief Secretary to the Lord Lieutenant", from the early 19th century until the end of British rule he was effectively the government minister with responsibility for governing Ireland; usually it was the Chief Secretary, rather than the Lord Lieutenant, who sat in the British Cabinet. The Chief Secretary was ex officio President of the Local Government Board for Ireland from its creation in 1872.

British rule over much of Ireland came to an end as the result of the Irish War of Independence, which culminated in the establishment of the Irish Free State. In consequence the office of Chief Secretary was abolished, as well as that of Lord Lieutenant. Executive responsibility within the Irish Free State and Northern Ireland was effectively transferred to the President of the Executive Council (i.e. the prime minister) and the Prime Minister of Northern Ireland respectively.

The dominant position of the Lord Lieutenant at Dublin Castle had been central to the British administration of the Kingdom of Ireland for much of its history. Poynings' Law in particular meant that the Parliament of Ireland lacked an independent power of legislation, and the Crown kept control of executive authority in the hands of the Lord Lieutenant and its own appointees, rather than in the hands of ministers responsible to the Irish parliament.
