Borsh (Albanian pronunciation: [ˈbɔɾʃ]; Albanian definite form: Borshi, [ˈbɔɾʃi]) is a maritime village, in the Albanian Riviera, in the former Lukovë municipality, Vlorë County, Albania. At the 2015 local government reform, it became part of the Himarë municipality. The village is inhabited by ethnic Albanians, many of whom have traditionally been Bektashi. In Borsh, the Lab dialect of Albanian is spoken.

Borsh borders with Fterra, Qeparo, Piqeras, Kuç, Çorraj, Kalasa, Zhulat, Tatzat, and has a population of 2,500 registered inhabitants.^{[citation needed]}

The region which Borshi is located was part of the Chaonia of the ancient region of Epirus. Borshi was probably fortified from antiquity and it belonged to Kemara (modern Himara) then part of the Chaonian tribal state, one of the main ancient Greek tribes in Epirus. In the Hellenistic period Borshi was a northwestern-most stronghold of the fortification system of Chaonia after Himara. The Chaonian fortification in Borsh of which Phoenice served as centre controlled a crucial road that connected Chaonia and southern Illyria.

The castle remained in use in Roman times and was refortified by the Emperor Justinian in the sixth century. Nothing is known of the settlement in the Byzantine era, until it is mentioned as Sopotos in 1258 when it was part of the Despotate of Epirus that grew out of the failing Byzantine empire. Borsh then went through a period of considerable turmoil, changing hands several times between the Despotate of Epirus and Norman crusades invaders before being taken by the Turks in 1431.

Fifty years later it was captured by Albanians led by Skanderbeg's son Gjon Kastrioti II, but was retaken by the Turks eleven years later and heavily refortified. On June 10, 1570 the castle of Sopot was taken by James Celsi, Proveditor of the Venetian navy, who left after leaving in charge the commander of Nauplion, Emmanuel Mormoris. This also caused part of the nearby Himariotes to submit to Venetian rule. The next year the Ottoman army recaptured it and took Mormori as a prisoner.

The 18th century was a turbulent economic time and due to Orthodox revolts and conflicts with Orthodox powers such as the Russian Empire, Ottoman governors at times applied pressures including drastic tax raises on the local Christian population as well as other pressures caused towns to convert. Borsh converted in 1744 and followed it up by raiding nearby Piqeras, which remained Christian.

The fortress was renovated again by Ali Pasha Tepelena, and it is these fortifications that visitors can view by taking the half-hour walk up to the 'castle rock', the limestone mount clearly visible above the old village. During Ali Pasha's reign, there were 700 houses at Borsh, and below the castle mount you can see a ruined mosque of Hajji Bendo and a madrese (a Muslim theological school), both of which were damaged in Ali Pasha's wars but survived, only to be destroyed in fighting after 1912 when the Turks left the region.

Between 1912 and 1914, serious inter-ethnic conflict took place between Greeks and Albanians, and significant portion of the old village was destroyed, however some buildings remain in fine condition. Modern Borsh was built after that, but became seriously depopulated, firstly due to malaria, and following severe reprisal killings by Germans in World War II. However, depopulation was balanced by an influx of refugees from Vlora, fleeing into partisan territory from the city which was heavily contested until late in the war. In 1914 the Greek military massacred many Albanians in Borsh.
