Kolonai (Ancient Greek: αἱ Κολωναί, romanized: hai Kolōnai; Latin: Colonae) was an ancient Greek city in the south-west of the Troad region of Anatolia. It has been located on a hill by the coast known as Beşiktepe ('cradle hill'), about equidistant between Larisa to the south and Alexandreia Troas to the north. It is 3.3 km east of the modern village of Alemşah in the Ezine district of Çanakkale Province, Turkey. Its name in Ancient Greek is the plural form of κολώνη (kolōnē), 'hill, mound', a common name for promontories with hills on them in the Eastern Mediterranean. It is not to be confused with Lampsacene Kolonai, a settlement situated in the hills above Lampsacus in the north-east of the Troad.
