Robert Bealknap (or Belknap) JP (died 19 January 1401) was a British justice. He is first mentioned in June 1351 in a papal register of indults issued to inhabitants of Great Britain, where he is called a "clerk, of the diocese of Salisbury" in Wiltshire. He next appears in 1353 as a member of a commission to survey Battle Abbey. This commission was followed by an extensive number of others, as evidenced by extant patent rolls, until 1388, most of which related to oyer and terminer, walliis et fossatis, gaol delivery, sewer, and the peace primarily, but not exclusively, in Kent and other parts of southeastern England. He was appointed a Justice of the Peace for Kent on 18 May 1362, and at the same time began serving as legal counsel. In July 1362 he served on a commission with William of Wykeham investigating lands granted to the Bishopric of Winchester, which Wykeham at that time held. From this point Belknap's career as a lawyer began to prosper; from 1371 he was retained as a lawyer by Westminster Abbey, and from 1374 by John of Gaunt. He was sent along with John Wycliffe and John Gilbert to Bruges in July 1374 to negotiate papal provisions; he returned in September and on 10 October he was made Chief Justice of the Common Pleas, and was Knighted on 28 December of that same year. From 1375 to 1388 he served as a Trier of Petitions in Parliament, and in 1376 he was involved in investigating Richard Lyons in Essex and Sussex after complaints of embezzlement.
