Ralph George Algernon Percy, 12th Duke of Northumberland, DL (born 16 November 1956), styled Lord Ralph Percy until 1995, is an English , hereditary peer and largely rural landowner.

Ralph Percy was born the second son (and one of seven children) of Hugh Percy, 10th Duke of Northumberland, and his wife, Elizabeth, née Lady Elizabeth Montagu Douglas Scott.

He attended Eton College and then studied History at the University of Oxford, and then land management with Reading University and worked in the Arundel Castle estate office for seven years, before moving back to Northumberland to manage the Alnwick estate for his elder brother Henry, the 11th Duke.

He succeeded in the dukedom in 1995 on the death of the 11th Duke, who had no offspring. As such, he was a member of the House of Lords until the passing of the House of Lords Act 1999 ended the right of hereditary peers to sit in the House. Hansard records no contributions to House of Lords work by Northumberland.

The Duke assists in managing Northumberland Estates (the corporation holding the ducal assets) which has many venture subsidiaries and associated trusts, which altogether own land and property in Northumberland, Scotland and to a lesser extent London, Surrey and Tyneside. Ralph Percy was ranked at number 248 in the Sunday Times Rich List 2011, with an estimated wealth of £315 million. He or the mentioned British active corporation is the owner of Alnwick Castle, an ancestral ducal seat, as well as Warkworth Castle and Prudhoe Castle in Northumberland; Syon House and Syon Park in London; Hulne Park and Hulne Priory at Alnwick; Albury Park in Surrey, and other listed buildings such as Brizlee Tower. Northumberland Estates manages 100,000 acres (400 km²): directly managing 4,000 acres (16 km²) of forestry and 20,000 acres (81 km²) of farmland, with approximately 100 tenant farmers managing the remaining bulk of the land.
