The Northwestern Bulgarian dialects are two closely related dialects of the Bulgarian language, which are located west of the yat boundary and thus are part of the Western Bulgarian dialects. The range of the dialects includes most of northwestern Bulgaria, to the west of the line between Nikopol, Pleven and Mezdra and to the north of the line between Vratsa and Belogradchik. They bear strong resemblance to their neighbouring Eastern Bulgarian dialects and with some exceptions, mainly the pronunciation of yat, have the same phonological and morphological features as the neighbouring subdialects of the Eastern Bulgarian Central Balkan dialect.
