Hugh Patrick Lygon (2 November 1904 – 19 August 1936 Rothenburg, Bavaria) was the second son of William Lygon, 7th Earl Beauchamp, and is often believed to be the inspiration for Lord Sebastian Flyte in Evelyn Waugh's Brideshead Revisited. He was a friend of Waugh's at Oxford (A. L. Rowse believed the two to be lovers), where both were members of the Hypocrites' Club, along with their contemporary Murray Andrew McLean.
Lygon died in Germany where he was on a motoring tour with his friend, the artist Henry Wynn (a son of Lady Newborough). Lygon was standing in the road to ask the way and fell backwards, hitting his head on a stone. He died later due to a fractured skull, having spent four days in a hospital in Rothenburg ob der Tauber. His body was later returned to England.
