Hugh Gilbert OSB (born 15 March 1952) is an English Catholic Benedictine monk who currently serves as the Bishop of Aberdeen.

[1] Gilbert was received into the novitiate of Pluscarden Abbey in Moray, Scotland, in March 1975, at which time he was given the religious name Hugh.

He made his temporary profession of monastic vows on 10 March of the following year and was then sent to the former Fort Augustus Abbey, located on the shores of Loch Ness, for studies and preparation for the priesthood.

He made his solemn profession of vows on 10 March 1979 and was ordained a priest in 1982 on the Feast of Saints Peter and Paul (29 June) by Mario Conti, then the Bishop of Aberdeen.

[1] Dom Alfred Spencer OSB, the first abbot in the history of the monastery,[2] subsequently appointed Gilbert to various duties in the community: sub-prior in 1984, novice master in 1985, and prior in 1990.
