Kalchas (Greek: Κάλχας, Turkish: Kalfa), is a village and a community in the municipality of Komotini, in the Rhodope regional unit, East Macedonia and Thrace, Greece.
The community consists of the villages Kalchas, Iampolis, Megali Ada and Mytikas.
[1] The village is crossed by a small stream (known locally by the name Trelocheimarros), tributary of the Vozvozis, that often overflows during the winter causing problems in transportation.
In 2011 the Army has placed a military bridge over the stream that improved significantly the transportation.
Just outside the village passes the single carriageway A23 expressway between the A2 motorway (Egnatia Odos) and the Greek-Bulgarian border at Makaza.
