Giles Daubeny or Daubeney, 1st Baron Daubeney KG (1 June 1451-12 May 1507) was an English soldier, diplomat, courtier and politician.
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. M.P. 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.
He was consulted before any one else by Reginald Bray to the projected invasion of Henry Tudor, Duke of Richmond, planned with Henry Stafford, 2nd Duke of Buckingham. On the failure of Buckingham's rebellion he with others fled to Richmond in Brittany, and he was consequently attainted in Richard's parliament. The custody of Petherton Park was granted to Richard FitzHugh, 6th Baron FitzHugh and Daubeney's lands in Somerset, Lincolnshire and Cornwall were confiscated.
