'Lords of Dol Amroth' is another name for the Princes of Dol Amroth, who ruled the lands of Belfalas in Gondor from the last millenium of the Third Age onward.

The first Lord of Dol Amroth was Galador, who was the son of Imrazôr the Númenórean.

According to legends, Imrazôr was wedded to an Elf maiden named Mithrellas and from them were descended all of the princes. This is never said definitively, so it cannot be proven, nor can it be disproven so it remains up for debate.

We do not know the names of all of the Lords of Dol Amroth, but those we do know are set forth here:

Galador
Adrahil
Imrahil

Prince Imrahil fought alongside Aragorn and Éomer and the armies of the West during the War of the Ring.
