William Haute (died 1462), of Bishopsbourne, Kent, was an English politician.
Haute was the eldest son of Sir Nicholas Haute, MP, of Wadden Hall in Waltham, Kent, and Alice, daughter of Sir Thomas Couen or Cawne of Ightham Mote. William's mother having died in March 1400, his father remarried to Eleanor Flambard (daughter of Edmund Flambard of Shepreth, Cambridgeshire), formerly the wife of Walter Tyrrell of Avon (between Ringwood and Christchurch), Hampshire.
William Haute thus became stepbrother to Sir John Tyrrell of East Horndon, later to be Speaker of the House of Commons and Treasurer of the Royal Household. In 1415, for Henry V's expedition to France, both Sir Nicholas Haute and his son William were mustered to join the retinue of Humphrey, Duke of Gloucester. William chose to enlist not in his father's company but in that of Tyrrell his stepbrother. Nicholas is thought to have died, perhaps of wounds, within a year or so after his return to England: William had succeeded to him by 1417, and Eleanor died in 1422.
Haute was a Member of Parliament for the Shire of Kent in 1419, and before October of that year he married Margaret Berwyk, daughter of Sir Hugh Berwyk of Frilsham, Berkshire. She was the sister and heiress of Thomas Berwyk, and the widow of Ralph Butler of Gloucestershire. William and Margaret had one daughter. He was appointed Sheriff of Kent for the year of 1420-21, during which he supervised elections for the county to three parliaments. From 1424 Haute held commission of the peace in Kent. During the 1420s his relations with John and Edmund Tyrrell presumably encouraged his continuing allegiance to the Duke of Gloucester.
