Smolyan is a town and ski resort in the very south of Bulgaria not far from the border with Greece. It is the administrative and industrial centre of the homonymous Smolyan Province. The town is situated in the valley of the Cherna ("Black") and the Byala ("White") Rivers in the central Rhodopes at the foot of the mountains' highest part south of the popular ski resorts Pamporovo and Chepelare. As of February 2011, it has a population of 30,283 inhabitants.

According to archaeological evidence, the area around Smolyan was first settled in the 2nd-1st millennium BC. In the Middle Ages it acquired its name from the Slavic tribe, the Smolyani, who settled in the region in the 7th century.

Due to its suitable location on top of Mount Rozhen, the Bulgarian National Astronomical Observatory is located nearby, with a planetarium in operation in the town. There is one theatre, the Rhodope Drama Theatre, and a gathering of theatre practitioners and scholars known as The Rhodopi International Theatre Laboratory is held every summer. There is also a regional historical museum founded in 1935.

The largest church in southern Bulgaria, the Cathedral of Saint Vissarion of Smolyan, was inaugurated in the city in July 2006.
