Jasło (Jassel, Jessel 1325 ) is a county town in south-eastern Poland with 38,104 inhabitants. It is situated in the Subcarpathian Voivodeship (since 1999); previously it was in Krosno Voivodeship (1975–1998). It is located in the heartland of the Doły (Pits), and its average altitude is 320 metres above sea level, although there are some hills located within the confines of the city. Patron of Jasło is Saint Anthony of Padua.
The name derives from Old Polish common word for the "manger" or "trough [trof]" which sounded "jasło" < *jesło (before the Lechitic umlaut). Plausibly, it comes from the Slavonic verb "to eat" - "jeść" < *jesti. The Modern Polish equivalent is "żłób" or more seldom "koryto" and the word "jasło" is forgotten in this meaning.
Jasło is an important railroad junction of southeastern Poland, with trains going into three directions - eastwards (to Zagorz), westwards (to Stróże) and northeast, to Rzeszów. Another line, along the Wisłoka to Dębica, was planned in the interebellum period. Construction on it began in 1938, but it was never completed because of World War Two.
