Przeworsk (Polish: [ˈpʂɛvɔrsk]; Ukrainian: Переворськ, romanized: Perevors'k; Yiddish: פּרשעוואָרסק, romanized: Prshevorsk) is a town in south-eastern Poland with 15,675 inhabitants, as of 2 June 2009. Since 1999 it has been in the Subcarpathian Voivodeship, and is the capital of Przeworsk County. The ancient Przeworsk culture was named after the town.

Przeworsk was a settlement since the 10th century, though evidence of human settlement in the general area is even older. It is first mentioned in historical records from the 13th century, and was granted its town charter in 1394. From 1772 the town was part of the Habsburg monarchy where it remained until 1918 when an independent Poland returned. Przeworsk is located on European route E40. It also is an important railway junction, with trains going in three directions – east (towards Przemyśl), west (towards Rzeszów) and north (towards Stalowa Wola).

Przeworsk has some 60 historic buildings, including two fortified Gothic abbeys, a town hall, the Lubomirski Palace in classical style, a baroque monastery, and an open-air museum (skansen). The town covers an area of 22 square kilometres (8.5 square miles).

In 13th century Ruthenian documents, Przeworsk was spelt Pereworesk. In the 14th and 15th centuries, its name was subject to variation. It was called Preworsko, Przeworsko, Przeworszko, Przeworscho, Przeiworsko, Przyworsko and Prziborsko. Since the 15th century, the name Przeworsko was most often used.

In the early Middle Ages, a defensive gord existed there. The area was included in the emerging Polish state by its first historic ruler Mieszko I in the 10th century. In 981 it was annexed from Poland by the Kievan Rus', and afterwards, in the High Middle Ages, it changed owners several times between Poland and the Rus', and even fell to the Mongol Empire in the mid-13th century. It was first mentioned in documents from 1280, when, after the Battle of Gozlice (23 February 1280) between Lesser Polish and Ruthenian-Tatar forces, Duke Leszek II the Black raided the Kingdom of Galicia–Volhynia, then vassal of the Golden Horde, capturing and setting alight the city of "Perevoresk"

"Въ лѣт̑ 6789 (1281) Иде Льстько на Лва и взѧ оу него городъ Переворескъ и исъсѣче и люди в нем̑ вси ѿ мала и до велика и город̑ зажьже и поиде назадъ во своӕси"

In the year 6789, (1281) Leszek attacked Leo I of Galicia, and took his city of Perevoresk and killed all in it, sparing neither young or old and having burnt the town to the ground he left.

After the Galicia–Volhynia Wars in mid-14th century, this territory of the Kingdom of Galicia–Volhynia, was reincorporated to the Kingdom of Poland by King Casimir III the Great and afterwards transformed into the Ruthenian Voivodeship within the larger Lesser Poland Province of the Polish Crown. Soon Polish settlers came to the deserted border areas, and in November 1387, King Władysław II Jagiełło ceded Przeworsk to the Voivode of Sandomierz, Jan of Tarnow, Leliwa coat of arms. Przeworsk grew fast, and on 25 February 1393, Jagiełło granted it a town charter.
