Grodzisko Górne [ɡrɔˈd͡ʑiskɔ ˈɡurnɛ] is a farming village in the administrative district of Gmina Grodzisko Dolne, within Leżajsk County, Subcarpathian Voivodeship, in south-eastern Poland. It lies approximately 4 kilometres (2 mi) north-west of Grodzisko Dolne, 9 km (6 mi) south of Leżajsk, and 36 km (22 mi) north-east of the regional capital Rzeszów.

The village is situated on the Wisłok river, which flows into the San river in Dębno, located near Leżajsk, on the edge of a Ruthenian settlement. The village separated itself as an independent administrative and economic unit from Grodzisko Dolne in 1786, along with another village called Grodzisko Nowe. In some cases, especially in immigration records, the two are referred to as one town called Grodzisko. The name Grodzisko comes from the word Gord, denoting a Slavic settlement. Grodzisko Górne itself was formerly a defensive settlement, as it is on the border with Ukraine. In 1881, an archaeological group from Kraków received a warrant to research the history of Grodzisko Górne. They found imprints of ancient settlements, probably dating back to immigrants from the 4th to 5th centuries. These archaeological works are still in progress today. It is bordered by a canyon, whose north bank provided much of the defense for this village. In the village there is an ancient manor house, which was opened for tourism in the 19th century. It is maintained by a priest from Grodzisko Górne, Wojciech Micha. The village employs many of the wage earners who reside in the rural commune of Grodzisko Dolne. The main industry is cloth manufacturing. Locally famous cloth markets are organized there. For farming, the major estate has 332 morgs of farmland and 58 meadows and gardens. The minor estate has 3200 morgs of farmland, 341 morgs of meadows and gardens, 216 morgs of pasture land and 428 morgs of forest. Today there is a three-grade schoolhouse and a post office in the village, serving its population of 5094, including 364 Jews.
