Evros (Greek: Περιφερειακή ενότητα Έβρου, romanized: Perifereiakí enótita Évrou) is one of the regional units of Greece. It is part of the region of East Macedonia and Thrace. Its name is derived from the river Evros, which appears to have been a Thracian hydronym. Evros is the northernmost regional unit. It borders Turkey to the east, across the river Evros, and it borders Bulgaria to the north and the northwest.

Its capital is Alexandroupolis. Together with the regional units Rhodope and Xanthi, it forms the geographical region of Western Thrace. The population density was 32 per km (2021).

Western Thrace (Greek: Δυτική Θράκη, IPA: [ðitiˈci ˈθɾaci]), also known as Greek Thrace or Aegean Thrace, is a geographical and historical region of Greece, between the Nestos and Evros rivers in the northeast of the country. It is the western part of Thrace; East Thrace, which lies east of the river Evros, forms the European part of Turkey, and the area to the north, in Bulgaria, is known as Northern Thrace. Greek Thrace is divided into three regional units (former prefectures): Xanthi, Rhodope and Evros, which together with the Macedonian regional units of Drama, Kavala and Thasos form the region of Eastern Macedonia and Thrace. The largest city of the region is Alexandroupolis.

Inhabited since Paleolithic times, it has been under the political, cultural and linguistic influence of the Greek world since the classical era. Under the Byzantine Empire, Western Thrace was part of the theme of Thrace and then of Macedonia and benefited from its position close to the imperial heartland and became a center of medieval Greek commerce and culture; later, under the Ottoman Empire, a number of Muslims settled there, marking the birth of the Muslim minority of Greece.

The Sanjak of Dedeağaç (Ottoman Turkish: Liva-i Dedeağaç, Greek: Υποδιοίκησις Δεδέαγατς), originally in 1878–1884 the Sanjak of Dimetoka (Liva-i Dimetoka, Υποδιοίκησις Διδυμοτείχου), was a second-level province (sanjak) of the Ottoman Empire in Thrace, forming part of the Adrianople Vilayet. Its capital was Dedeağaç, modern Alexandroupolis in Greece.
