Debren is a village in Garmen Municipality, in Blagoevgrad Province, Bulgaria.[2] It is situated in the Dabrash part of the Rhodope Mountains 2.5 kilometers southeast of Garmen and 110 kilometers southeast of Blagoevgrad.
The village has a very long history. There are two stone-made Roman bridges in the old village, that existed until 1968 year, when the whole village was moved from its previous mountainous location to a new one - lower and closer to the Mesta river, where the land is arable.

There are also some inhabited houses, but most of the buildings are in ruins. The village was mentioned first by the modern name in 1660 in Ottoman documents. In the 19th century the village was described as a Muslim village inhabited with people of Pomak origin.
The new village was built with central water supply and sewerage and straight streets with two story houses.
