Gefyra (Greek: Γέφυρα, literally meaning "Bridge", until 1926 Τοψίν/Topsin, Bulgarian: Топчиево/Topchievo, Turkish: Topçin) is a village and a community of the Chalkidona municipality,[2] about 20 km northwest from Thessaloniki.

[3] There is a highway junction near Gefyra, where the European route E75 and E86 meets.

The village is the site of the surrender of the Ottoman garrison of Thessaloniki under Hasan Tahsin Pasha to the Greek army under Crown Prince Constantine during the First Balkan War (1912).

The villa where the surrender took place now houses the Balkan Wars Museum.
