The Dupnitsa dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in the region of Dupnitsa in central western Bulgaria. It is transitional between the Samokov dialect to the east and the Blagoevgrad-Petrich dialect to the south.

Phonological and morphological characteristics

• щ/жд (ʃt/ʒd) for Proto-Slavic *tʲ/*dʲ (as in Standard Bulgarian) - леща, между (lentils, between). The future tense particle, however, is че: че че'темe vs. Standard Bulgarian ще четем (we will read)
