Devol (Bulgarian: Девол) also Deabolis or Diabolis, (Greek: Δεάβολις) was a medieval fortress and bishopric in western Macedonia, located south of Lake Ohrid in what is today the south-eastern corner of Albania (Devoll District). Its precise location is unknown today, but it is thought to have been located by the river of the same name (today Devoll River), and on the Roman Via Egnatia road.
