Aubrey Beauclerk, 5th Duke of St Albans (3 June 1740 – 9 February 1802) was a British landowner, and a collector of antiquities and works of art.

In 1779, Beauclerk financed an excavation with Thomas Jenkins at Centocelle, which produced several ancient sculptures.

Some of the sculptures were sold to Giovanni Battista Visconti for the Museo Pio-Clementino at the Vatican in Rome, and others to the British collector, Henry Blundell; many were displayed at Beauclerk's house at Hanworth by 1783.

On 4 May 1763 Beauclerk married Lady Catherine Ponsonby (1742–1789), daughter of William Ponsonby, 2nd Earl of Bessborough (who served in both the Irish and the British House of Commons, and held office as a Lord Commissioner of the Admiralty, Lord Commissioner of the Treasury, Postmaster General of the United Kingdom, a Privy Counsellor, and Chief Secretary for Ireland)[3] and Lady Caroline Cavendish (eldest daughter of William Cavendish, 3rd Duke of Devonshire).

[2] Together, Lady Catherine and Lord Aubrey were the parents of seven children:[2] Beauclerk died in 1802, and is buried in St George's Church, Hanworth.
