Protokklisi (Greek: Πρωτοκκλήσι meaning the first church, Bulgarian: Башклисе) is a village and a community in the central part of the Evros regional unit in Greece.

Protokklisi is located about 15 km northwest of Soufli, in the valley of a right tributary of the river Evros.

The name of the village during the Ottoman rule was Bashklise (Başkilise in Turkish, Башклисе Bašklise in Bulgarian).

[2] According to professor Lyubomir Miletich, the 1912 population contained 100 Bulgarian families.

As a result its Bulgarian population was exchanged with Greek refugees, mainly from today's Turkey.
