Hugh Percy, 1st Duke of Northumberland, KG, PC (c. 1714 – 6 June 1786) was an English peer, politician, and landowner.

In 1766, the earl was created 1st Duke of Northumberland and was created Baron Lovaine on 28 June 1784, with a special remainder in favour of his younger son, Algernon[3] (in reference to the Louvain family of the Landgraviate of Brabant, which married the Percy heiress, was the origin of the Percy family of England).

[citation needed] He took a somewhat prominent part in politics as a follower of Lord Bute, and was one of George III's confidential advisers.

[3] Sir Hugh and Lord Brooke (later created Earl of Warwick) were the most important patrons of Canaletto in England.

At Alnwick Castle, Northumberland, the Duke employed James Wyatt, whose work has been effaced by later remodellings.
