The Prior of Whithorn was the head of the monastic community at Whithorn Priory, attached to the bishopric of Galloway at Whithorn. It was originally an Augustinian establishment, but became Premonstratensian by the time of the second or third known prior. As most of the priors of Whithorn appear to be native GalwegianGaels, it would appear that most priors before the 16th century at least were drawn from region, something unusual in medieval Scotland. The following is a list of abbots and commendators.
