Francis Ingram-Seymour-Conway, 2nd Marquess of Hertford, KG, PC, PC (Ire), styled The Honourable Francis Seymour-Conway until 1750, Viscount Beauchamp between 1750 and 1793, and Earl of Yarmouth between 1793 and 1794, was a British peer and politician. He held seats in the Irish House of Commons from 1761 to 1776 and in the British House of Commons from 1766 to 1794. He served as Chief Secretary for Ireland under his father. He subsequently held positions in the Royal Household, including serving as Lord Chamberlain between 1812 and 1822.

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, roughly equivalent to the role of a Secretary of State, such as the similar role of Secretary of State for Scotland. 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.
