William Bonville, 1st Baron Bonville (c. 1392–93 – 18 February 1461), KG, of Shute, Devon, was an English nobleman, soldier, and administrator. He was a staunch Yorkist during the Wars of the Roses, and was executed following the Lancastrian victory at the Second Battle of St Albans by order of King Henry VI's Queen Consort, Margaret of Anjou.

The Bonvilles were an old West Country family. The date of William Bonville's birth is uncertain. Cokayne states that he was born 30 August 1393, while Richardson states that various documents indicate he was four years of age in 1397, 16 years of age in 1408, and 21 years of age in 1414. He was born at Shute, Devon, the son of Sir John Bonville (c. 1371 – 21 October 1396), son and heir apparent of Sir William Bonville (c. 1332 – February 1408) of Shute by his first wife, Margaret D'Aumarle (died 25 May 1399), the daughter of Sir William D'Aumarle.

Bonville's mother was Elizabeth FitzRoger (15 August 1370 – 15 April 1414), the only child and sole heiress of John FitzRoger (died 1370–72) of Chewton, Somerset and his wife Alice (died 27 March 1426). John FitzRoger was the 3rd son of Sir Henry FitzRoger (died 1352) of Chewton by his wife Elizabeth de Holland (died 13 July 1387). Elizabeth de Holland was a daughter of Robert de Holland, 1st Baron Holand, by his wife Maud la Zouche. Maud la Zouche was a daughter of Alan la Zouche, 1st Baron la Zouche of Ashby.). Elizabeth FitzRoger survived her husband and remarried to Richard Stucley (died before 1441) of Ridgewell, Essex, Member of Parliament for Sussex, in 1415, March 1416 and 1417, by whom she had two sons, Roger Stukeley and Hugh Stukeley (founder of the prominent Stucley family of Affeton in Devon), who were thus Bonville's brothers of the half blood.
