Kastanies (Greek: Καστανιές, meaning "chestnuts", Turkish: Kestanelik which means "chestnut" too) is a town located in northern part of the regional unit of Evros, Greece, and is part of the municipal unit of Vyssa.

The Greek National Road 51/E85, which connects Alexandroupoli with the Bulgarian border near Svilengrad passes west of Kastanies.

A smaller road connecting the E85 with Edirne in Turkey by way of the border crossing Karaağaç passes through Kastanies.

The village during the Ottoman administration was called "Çörekköy"[2] and in the past had experienced great economic growth, from the cultivation of the broom.

In March 2018, at the Greek-Turkish border in Kastanies, two Greek officers were captured by a multi-member Turkish patrol.
