Dragasia (Greek: Δραγασιά, before 1927: Δίσλαπον – Dislapon),[2] is a small town located in the municipal unit of Tsotyli, western Kozani regional unit, itself in the Greek region of Macedonia.

[3] In the Late Ottoman period, it was inhabited by Vallahades; in the 1900 statistics of Vasil Kanchov, where the town appears under its Bulgarian name "Lislap'", it was inhabited by some 100 people all marked as "Greek Muslims".

[4] Dislapon was a mixed village and a part of its population were Greek speaking Muslim Vallahades.

[5] The 1920 Greek census recorded 414 people in the village, and 70 inhabitants (15 families) were Muslim in 1923.

[6] Following the Greek–Turkish population exchange, Greek refugee families in Dislapon were from East Thrace (1) and Pontus (20) in 1926.
