Skelivka (Ukrainian: Скелівка; Polish: Felsztyn) is a village in Lviv Oblast, Sambir Raion, Ukraine on the Strwiąż River.

Felsztyn, as the settlement is called in Polish, was founded in 1374 by King Ludwik Węgierski, on lands granted by Duke Vladislaus II of Opole to the Herburt noble family, and received town privileges under the Magdeburg rights in 1380.

Additional privileges were granted to the town in 1488 by Casimir IV Jagiellon and in 1551 by Sigismund II Augustus.

The name was historically variously spelled as Fulsztyn, Folsteyn, Felstin, Fullensteyn, Fulsthine and Fulstin (1593).

[2] During the joint German-Soviet invasion of Poland, which started World War II, Felsztyn was occupied by the Soviet Union on September 17, 1939, and then by Nazi Germany from 1941 to 1944.

Until World War II, the town had a Roman Catholic church (and adjacent cemetery) which catered to the Polish population.
