Cieszanów [t͡ɕɛˈʂanuf] (Ukrainian: Тішанів or Цішанів or Чесанів, Tishaniv or Tsishaniv or Chesaniv; Yiddish: ציעשאנאָוו Tsyeshanov) is a town in Lubaczów County, Subcarpathian Voivodeship, Poland.

In the Middle Ages, sandy shores of the Brusienka river attracted Slavic Lechitic settlers, who probably in the 10th century established a gord here.

Furthermore, a merchant road to Jarosław was established nearby, so a nobleman Stanisław Cieszanowski (Jelita coat of arms), who was owner of the village, applied for town charter.

On May 14, 1590 in Warsaw, King Sigismund III of Poland granted Magdeburg rights to the new town, which was named Cieszanów, after the Cieszanowski family.

Due to proximity of the border with Russian-controlled Congress Poland, Cieszanów and its vicinity was used for smuggling of weapons, ammunition and volunteers during the January Uprising (1863–1864).

In May 1863, a large military hospital for Polish rebels was established here, and Austrian government, uneasy about the situation, sent to Cieszanów a squadron of Hungarian mounted troops, which guarded the borderline.

[3] On September 7, 1939, Cieszanów was bombed by the Luftwaffe, and five days later, first Wehrmacht units entered the town, arresting members of local government.

The Germans soon retreated (see Molotov–Ribbentrop Pact), replaced by the Red Army, but in early October 1939, Cieszanów became part of General Government’ Zamość County.
