Henry Blundell (1724 – 28 August 1810) was an English art collector.
Blundell was born at Ince Blundell, Lancashire. A Catholic, like his friend and fellow collector Charles Townley (who encouraged Blundell's collecting and introduced him to Thomas Jenkins) he was thus barred from the British university system and was educated at the college of the English Jesuits at St Omer and the English College at Douai. He married Elizabeth, daughter of Sir George Mostyn, bt, of Talacre, Flintshire in 1760 (commissioning her portrait from Joshua Reynolds) and had his family estates settled on him by his father in 1761. He also received a fortune from an inheritance from the death of a member of his mother's family without a male heir, further increased by income from his mother's estates and by his wife's and father's death in 1767 and 1773 respectively.
His high income from various sources enabled him to collect classical sculpture and old master paintings (including ones by or after Poussin, Ruisdael, Brueghel, Jacopo Bassano and Andrea del Sarto, and even a copy of Veronese's The Wedding at Cana, commissioned during a visit to Paris), to improve Ince Blundell Hall and to buy and commission artworks from current artists like Richard Wilson, Canova, Gavin Hamilton and Anton Raphael Mengs. He went on a Grand Tour to Italy in 1776, visiting Milan, Venice, Ancona, Rome and Naples. There he made his first classical sculpture purchase via Jenkins (a seated philosopher and eighty pieces from the Villa Mattei), though on later visits to Rome he came to mistrust him and relied more on Father John Thorpe. He tended to collect wholesale rather than discriminatingly, as with his group from the Villa Borrioni (probably also in 1777), and also to knowingly purchase modern copies (such as by Giuseppi Angelini and Carlo Albacini) and classical works imaginatively restored by dealers such as Bartolomeo Cavaceppi and Giovanni Volpato.
Making other trips to Rome in 1782–3, 1786, and 1790, his collecting patterns improved, in 1783 acquiring the high quality Minerva from Palazzo Lante, but the outbreak of the French Revolutionary Wars put a pause to his collecting and transferred his attention to creating new buildings at Ince Blundell for his collections (though he did buy at the 1800 and 1801 English sales of Lord Cawdor and Lord Bessborough's collections). He also became the Liverpool Academy of Arts's first patron on its foundation in 1810 and was active in Liverpool public life (though unable to hold public office, as a Catholic). He died at Ince Blundell.
