Madan (Bulgarian: Мадан [mɐˈdan]) is a town in Smolyan Province, the very south of Bulgaria in the Yellow Share of the Rhodope Mountains.

In the central part of the Yellow Share rise the peaks Buchovitsa (1404 m), Veternitsa (1372 m) and Petrovitsa (1309 m).

From all sides the Yellow Share is separated by mountain-spurs, whose segmentations gradually slope down and vanish into the valleys of the rivers.

Madan is an ancient ore-miners' settlement, the extraction of lead ore having begun around 5th-4th century BC.

Most of the town's population consists of local Pomaks and a minority of Eastern Orthodox Bulgarians.
