Thesprotia (Greek: Θεσπρωτία) is one of the regional units of Greece. It is part of the Epirus region. Its capital is the town of Igoumenitsa. It is named after the Thesprotians, an ancient Greek tribe that inhabited the region in antiquity.
The territory of Thesprotia remained under Ottoman rule until 1913, when it was annnexed by the Greek state after the First Balkan War. Until 1937, when the separate prefecture of Thesprotia was established, the area was part of the Ioannina Prefecture.
Geography and climate 
Thesprotia borders Albania to the north, the regional unit of Ioannina to the east and Preveza to the south. The Ionian Sea lies to the west. Much of the regional unit is mountainous. Most farmland is located in the valleys in the central, southern and the western part. Two of Thesprotia's rivers are legendary: the Thyamis and the Acheron of Greek mythology, lined with reedbeds and plane trees.
Thesprotia's coastal climate is Mediterranean. Cold winters of a semi-alpine climate dominate the eastern part and higher elevations.
The regional unit Thesprotia is subdivided into 4 municipalities. These are (number as in the map in the infobox):
Thesprotia was established as a prefecture in 1937 (Greek: Νομός Θεσπρωτίας). As a part of the 2011 Kallikratis government reform, the regional unit Thesprotia was created out of the former prefecture Thesprotia. The prefecture had the same territory as the present regional unit. At the same time, the municipalities were reorganised, according to the table below.
|New municipality||Old municipalities||Seat|
- Province of Thyamida - Igoumenitsa
- Province of Filiates - Filiates
- Province of Margariti - Margariti
- Province of Souli - Paramythia
Note: Provinces no longer hold any legal status in Greece.
Thesprotia is traditionally one of the poorest and most remote prefectures of Greece. The main economical activities are agriculture and tourism, with agriculture as historically the main economical activity.
In 1996, construction began on motorway 2, officially called Egnatia Odos. The road, which links the Ionian coast at Igoumenitsa to Thessaloniki, was opened to traffic in 2009. Other important roads in Thesprotia include the Greek National Road 6 (Igoumenitsa - Ioannina - Larissa) and Greek National Road 18 (Filiates - Paramythia - Preveza).
The port of Igoumenitsa serves ferry routes to the islands of Corfu and Paxoi (includes Antipaxoi), as well as Italy.
