Sir Robert Poyntz (died 1520),[3] lord of the manor of Iron Acton in Gloucestershire, was a supporter of the future King Henry VII at the Battle of Bosworth in 1485.
He was the eldest son and heir of John Poyntz (died 1465/72[4]), of Iron Acton, by his wife Alicia Cocks of Bristol,[5] who survived him and remarried to Sir Edward Berkeley of Beverstone Castle[6] in Gloucestershire.
Sir Robert's younger brother was Thomas Poyntz (died 1501), an Esquire of the Body of King Henry VII at the baptism of his first-born son Prince Arthur, who married a certain Jane, the second wife and widow of Walter Devereux, 8th Baron Ferrers of Chartley(c.1432–1485), Knight of the Garter.

Two remnants of his chest-tomb survive in the Gaunt's Chapel, being wooden panels decorated with Gothic canopy-work, each showing an heraldic shield.
