Sopot (Bulgarian: Сопот [ˈsɔpot]) is a Bulgarian town situated in the fertile sub-Balkan mountain valley of Karlovo (which is the western part of the famous Rose Valley), immediately below the steep southern slopes of the Troyan Balkan Mountain (Central Stara Planina).

According to Konstantin Jireček, the toponym is of Proto-Slavic origin, as indicated by the large number of identical placenames all around the Slavic world.

During the Bulgarian National Revival (18th and 19th centuries) it was called "Golden Sopot" because of its flourishing development in the crafts and trade.

The citizens of Sopot manufactured homespun, braids, fur and leather of high quality and traded predominantly round the Ottoman Empire.

The pioneering Bulgarian educator Nedelya Petkova (1826–1894) began her career a student at the monastery school of the "Holy presentation of the Blessed Virgin" convent in Sopot.
