Vladaya (Bulgarian: Владая, pronounced [vɫɐˈdajɐ]) is a village on the Vitosha and Lyulin mountains in western Bulgaria at an altitude of about 1000 m. In the 2011 census in Vladaya were counted 4043 residents, which makes it the tenth largest village in Bulgaria.

However, only a small neighborhood falls within Lyulin and the village is mostly situated on the northwestern parts of Vitosha.

The history of the village reflects the fate of the nearby Sofia city.

Over the centuries, different tribes and peoples invaded the area - Macedonians, Celts, Romans, Goths, Bulgarians, Turks, Russians and others.

Etymological studies derive it from the genitive and accusative form of the Bulgarian personal name Vladay.
