John William Ponsonby, 4th Earl of Bessborough PC (31 August 1781 – 16 May 1847), known as Viscount Duncannon from 1793 to 1844, was a British Whig politician. He was notably Home Secretary in 1834 and served as Lord Lieutenant of Ireland between 1846 and 1847, the first years of the Great Famine.
A member of the prominent Ponsonby family of Cumberland, he was the eldest son of Frederick Ponsonby, 3rd Earl of Bessborough, and Lady Henrietta Frances, daughter of John Spencer, 1st Earl Spencer. Sir Frederick Cavendish Ponsonby and William Ponsonby, 1st Baron de Mauley, were his younger brothers, while Lady Caroline Lamb was his younger sister. Ponsonby's mother was Lord Granville's lover prior to his marriage to Lady Harriet Cavendish, the Countess of Bessborough's niece. Lord Granville fathered two illegitimate children through her: Harriette Stewart and George Stewart. Lord Bessborough was educated at Harrow and Christ Church, Oxford.
He was First Commissioner of Woods and Forests under Lord Grey (1831–1834) and served under Lord Melbourne in that office (1835–1841), briefly as Home Secretary (1834), and as Lord Privy Seal (1835–1839). Later, he served as Lord Lieutenant of Ireland under Lord John Russell from 1846 until his death on 16 May 1847. He was made a Privy Counsellor in 1831 and in 1834, ten years before he succeeded his father, he was created Baron Duncannon, of Bessborough in the County of Kilkenny. He was Lord Lieutenant of Kilkenny from November 1838 until his death.
