Czaszyn [ˈt͡ʂaʂɨn] is a village in the Sanok County in the East Małopolska in the Lesser Beskid mountains.

Czaszyn is currently situated in the Subcarpathian Voivodship (since 1999), previously in Krosno Voivodship (1975–1998) and Sanok district, (10 miles east of Sanok), located near the towns of Medzilaborce and Palota (in northeastern Slovakia).

Then the Polish Communist government's brutal Akcja Wisła resettlement project deported many Ukrainian residents to leave Czaszyn on 29 April 1947, for the former eastern territories of Germany.

It is situated below the main watershed at the foot of the Słonne Mountain near the Osława River at an elevation of 270 meters.
