Robert of Winchester (died 1180) was abbot of Glastonbury. Formerly prior of Winchester, he became abbot of Glastonbury in succession to Henry of Blois in 1173. Robert accepted a position as canon of Wells Cathedral, in a manoeuvre that ended unsuccessfully. Two churches, at Pilton and South Brent, the patronage of which was disputed between Wells Cathedral and Glastonbury Abbey— then fell under the jurisdiction of Wells.
