Fat Lips (or Fatlips) is the name given to a legendary spirit dwelling in Dryburgh Abbey in Berwickshire, Scotland.
The spirit was associated with a hermit woman who took up residence in a vault among the ruins of the abbey some time after the 1745 Jacobite Rebellion. The woman claimed that the spirit tidied the room whilst she was away, and kept the cell she lived in dry by stamping moisture away from the ground with his heavy iron boots.
