The Sanok-Turka Mountains (Polish: Góry Sanocko-Turczańskie; Ukrainian: Сяноцько-Турчанські гори) are a mountain range in the Eastern Beskids, within the Outer Eastern Carpathians.

The Sanok-Turka mountain range stretches on an area of 930 km2 to the north of the Bieszczady Mountains, and to the south of the Przemyskie Upland, between the valleys of the middle San and Stryi River.

The southern border is generally carried through the ridges of the Otryt mountain range and through the San where the Tyrawski river joins as a tributary, although sometimes the Otryt mountain range is linked with the Sanocko-Turczańskie mountains, then the southern border is the Upper San river.

The characteristics of the mountain range is that they had a straight stretch which is separated by valleys of rivers or streams.

According to the story of Tacitus, this area was described as Bastarnae Alpes, qui alias Carpathia Montes on the outskirts of the Hercynian Forest.
