Phineas Finn is a novel by Anthony Trollope and the name of its leading character. The novel was first published as a monthly serial from October 1867 to May 1868 in St Paul's Magazine. It is the second of the "Palliser" series of novels. Its sequel, Phineas Redux, is the fourth novel in the series. The character of Phineas Finn is said to have been partly inspired by Sir John Pope Hennessy (grandfather of the museum director of the same name), a Roman Catholic from Cork, who was elected as an "Irish Nationalist Conservative" Member of Parliament for King's County in 1859.
