Kleisoura (Greek: Κλεισούρα, also Βλαχοκλεισούρα, Vlachokleisoúra; Aromanian: Klisoura) is a traditionally Aromanian (Vlach) settlement and a former municipality in Kastoria regional unit, West Macedonia, Greece. Since the 2011 local government reform, it is part of the municipality of Kastoria, of which it is a municipal unit. Population 259 (2011). On 5 April 1944, the German occupation forces executed 280 inhabitants as retaliation for the killing of three Nazi soldiers by ELAS guerrilla forces operating under Alexis Rosios just outside the village at the location Ntaouli. According to testimonies, SS forces under Karl Schümers entered the village and started setting houses on fire and killing the women, children and elderly people who had been left in the village, as most men had fled to the nearby mountains to avoid execution.
Army General Constantine Lianis (Κωνσταντίνος Λιάνης), a war hero, and one of the founders of the Greek secret services (KYP), originated from Kleisoura. His daughter is Dimitra Liani (Δήμητρα Λιάνη), who became first the lover, and then the third and last wife of Prime Minister Andreas Papandreou.
