Dor-en-Ernil means 'Land of the Prince', and is named so for the Princes of Dol Amroth who ruled that land.

It is difficult to discern the exact boundaries of the land, but we do know that it encompassed much of the southern coastland of Gondor. Very possibly, the borders were from the River Ringló to the River Gilrain and to the northernmost part of the cape of Belfalas.
