Giles Daubeney, 1st Baron Daubeney, KG (1 June 1451 – 21 May 1508) was an English soldier, diplomat, courtier and politician.
Giles Daubeney was the eldest son and heir of Sir William Daubeney (1424-1460/1) of South Ingelby in Lincolnshire, and South Petherton and Barrington Court in Somerset, MP for Bedfordshire 1448/9, and Sheriff of Cornwall 1452/3. His mother, Alice Stourton, was the youngest of the three daughters and co-heiresses (by his 3rd wife Katherine Payne) of John Stourton (died 1438), builder of the Abbey Farm House, Preston Plucknett and owner of Brympton d'Evercy in Somerset, who was seven times MP for Somerset, in 1419, 1420, December 1421, 1423, 1426, 1429 and 1435. He was probably born at South Petherton in Somerset, where his father seems to have been resident.
In 1475 he went over to France with Edward IV, from whom he obtained a license before going to make a trust-deed of his lands in the counties of Somerset and Dorset. He was then designated esquire, and he went in command of four men-at-arms and fifty archers. Soon after he became one of the esquires for the king's body, and two years later he had a grant for life of the custody of the king's park at Petherton, near Bridgwater. Member of Parliament for Somerset in 1477–8, he was knighted before the end of King Edward's reign. He was also present at the coronation of Richard III on 6 July 1483.
