Sobień (Soban 1372, castro Sobyen 1460) – Medieval castle in the San river valley, at the feet of Eastern Carpathian mountains, in the Manasterzec village in Lesko County, Subcarpathian Voivodeship.
First mentioned as Soban, it was a Royal castle guarding the merchant route along the San River. The castle was built by order of King Casimir the Great in 1340.
In 1389 Władysław II Jagiełło conferred the castle to a noble family of Kmita.
The castle was destroyed in 1474 and again in 1512 by Hungarian forces. In 16th century the Kmita family sold the estates and the castle to Stadnicki family, who held it until 1713.
