Teteven (Bulgarian: Тетевен) is a town on the banks of the Vit river, at the foot of Stara Planina mountain in north central Bulgaria. It is the administrative centre of the homonymous Teteven Municipality which is a part of Lovech Province. As of December 2009, the town has a population of 10,613 inhabitants.
The town was first mentioned in a written document in 1421. It is thought that the town's name comes from the family of a certain Tetyo (Tetyov rod), who settled in the area and founded the town. Older variants of the town's name found in documents are Tetyuven and Tetyuvene.
A thriving city in the 16th and 17th century, Teteven was raided by organized Turkish brigand groups in 1801, burnt down and almost completely destroyed, with only 4 houses surviving out of a total of 3,000. The town later revived and was active in the armed struggle for Bulgarian independence in the 19th century, sheltering a revolutionary committee from Vasil Levski's organized rebel network.
Each summer a large chess tournament, one of the biggest events in Bulgaria's chess calendar, is held in Teteven.
