The Abbot and then Commendator of Melrose was the head of the monastic community of Melrose Abbey, in Melrose in the Borders region of Scotland. The abbots of the earlier Northumbrian foundation from Lindisfarne are not included here. The second abbey was founded in 1136 on the patronage of David I, King of Scots, by Cistercian monks from Rievaulx Abbey, Yorkshire. Control of the abbey was secularized in the 16th century and after the accession of James Stewart, the abbey was held by commendators. The last commendator, James Douglas of Lochleven, resigned the abbacy to William Douglas, 6th Earl of Morton in December 1606, and the abbey itself to the king in 1608. The abbey was then erected into a secular lordship for viscount Haddington, John Ramsay, who in 1609 was created "Lord Melrose". Lochleven however resumed the title of commendator in 1613 until his death in 1620.

St Mary's Abbey, Melrose is a partly ruined monastery of the Cistercian order in Melrose, Roxburghshire, in the Scottish Borders. It was founded in 1136 by Cistercian monks at the request of King David I of Scotland and was the chief house of that order in the country until the Reformation. It was headed by the abbot or commendator of Melrose. Today the abbey is maintained by Historic Environment Scotland as a scheduled monument.
