Gilbert the Great (died 17 October 1167) was an English monk and theologian who served as the ninth abbot of Cîteaux from 1163 until his death.
[1] Prior to coming to Cîteaux, Gilbert served as the abbot of Ourscamp Abbey [fr] from 1143.
In 1165, he received from Pope Alexander III the exemption of the Cistercians from episcopal jurisdiction.
When, in 1166, the dispute between King Henry II of England and Archbishop Thomas Becket embroiled the Cistercians, Gilbert asked Becket to leave Pontigny Abbey, where he was staying.
Of his writings, three letters to King Louis VII of France are preserved.
