Jaśliska [jaˈɕlʲiska] is a village in Krosno County, Subcarpathian Voivodeship, in south-eastern Poland, close to the border with Slovakia.

In the early years of Polish statehood, the area of Jasliska probably belonged to the tribe of the Vistulans, which in the late 10th century became part of Poland.

Hohstadt, whose name was later changed into Jasliska, had a vogt, and a medieval market square with a town hall, modelled after nearby Biecz.

The town was burned to the ground, so on May 1, 1506, in Lublin, King Aleksander Jagiellonczyk granted additional privileges to Jasliska, including weekly fairs on every Tuesday, and extempting its residents from taxes for the period of eight years.

In 1559, Jasliska was granted the right to stock wine in cellars, but at the same time, merchants bypassed the town, due to high duties.

Jasliska prospered in the period known as Polish Golden Age, when it belonged to Biecz County of Kraków Voivodeship.

The elderly and children were executed by firing squad in the forest on the Błudna Mountain slope, between Barwinek and Tylawa.
