Dercongal Abbey (or Holywood Abbey) was a Premonstratensian monastic community located in Dumfriesshire, Scotland. The date of its foundation is not known, but it was certainly in existence as a Premonstratensian monastic community by 1225. The founder was presumably Alan, Lord of Galloway. Dercongal seems to come from Doire Congaill, Congall's oak-copse, Congall (Welsh, Cinvall) being a saint venerated by the natives of the area.
