TROAS, (anc. geog.) a district comprised between the two Mysiæ; and therefore distinct from the kingdom of Troy and the possessions of Priam; and was the Troas Propria; for, according to Homer, both the Mysiæ were under the empire of the Trojans, from the neighbourhood of the river Ælepus, and that of Cyzicene, to the river Caycus, (Strabo); called Phrygia Minor, (Ptolemy). Alexandria, a town in this district, was also called Troas, a Roman colony.
