Jocelin (or Jocelyn) (died 1199) was a twelfth-century Cistercian monk and cleric who became the fourth Abbot of Melrose before becoming Bishop of Glasgow, Scotland. He was probably born in the 1130s, and in his teenage years became a monk of Melrose Abbey. He rose in the service of Abbot Waltheof, and by the time of the short abbacy of Waltheof's successor Abbot William, Jocelin had become prior. Then in 1170 Jocelin himself became abbot, a position he held for four years. Jocelin was responsible for promoting the cult of the emerging Saint Waltheof, and in this had the support of Enguerrand, Bishop of Glasgow.
