Bylazora or Vilazora (Ancient Greek: Βυλάζωρα) was a Paeonian city from the period of early classic antiquity.

Bylazora is also mentioned by Livy in his "The History of Rome" when Perseus in 168 BC arranged military support from the Gauls who were campaigning in Desudaba, Maedica, requesting the Gaulish army to shift their camp to Bylazora, a place in Paeonia, and their officers to go in a body to him at Almana on the River Axius.

The geographic dominance over the surrounding valley has determined the communications significance of the city in ancient times.

Ancient Bylazora was the largest and most significant city of Paionia, mentioned in the records of Polybius and Titus Livius.

In that manner he was able to move the ancient Bylazora on the bank of the Axius River to the inland of Paeonia at Kneze near Sveti Nikole.
