John Grandisson (died 1369) was a medieval Bishop of Exeter. He gave his name to several cultural items that are now in the British Library, the British Museum and the Louvre.

Grandisson was born at Ashperton near Hereford in 1292. His father William, Lord de Grandisson, was a Burgundian in the household of Edmund, Earl of Lancaster, brother of King Edward I of England. He studied theology at the University of Paris, and became a prebendary of Masham in York Minster at the age of 17. He became Archdeacon of Nottingham at 26, then succeeded his younger brother Thomas as a prebendary of Heydore at Lincoln Cathedral.

Grandisson changed his family's coat of arms by substituting a mitre for the normal central eaglet making the arms unique to him. He used this as well as the normal version. Grandisson was the second son of his father so when his elder brother died in 1358 without an heir he became the head of the family.

Grandisson was nominated as bishop on 10 August 1327 and consecrated on 18 October 1327. He died 16 July 1369. Grandisson was buried in the mortuary chapel of St Radegund on the south side of the central doorway of the west front of Exeter Cathedral. His tomb was destroyed during the reign of Elizabeth I.

While bishop, Grandisson outlawed a popular cult that was being promoted by a house of canons in . In addition, in 1335, he founded the original Kings School (Ottery St Mary) (then known as the College of Secular Canons) establishing it as a choir school for eight boys and a Master of Grammar.
