Sebiș (Hungarian: Borossebes) is a town in Arad County, western Transylvania, Romania. Situated from the county capital, Sebiș is one of the most important urban centres in the Crișul Alb valley. It administers three villages: Donceni (Dancsfalva), Prunișor (Kertes), and Sălăjeni (Szelezsény).
The town lies on the banks of the river Sebiș and its tributaries, the Laz and the Minezel. Its territory occupies in the greater Sebiș Basin, which is a sub-unit of the Crișul Alb Basin.

The first documentary mention of the locality dates back to the year 1552, while later, in 1746 Sebiș had a market status (Romanian; Moldavian; Moldovan: italic=no|opidum Sebes). Donceni was registered in 1439, Prunișor in 1406 and Sălăjeni in 1574.
Until the end of the 18th century Sebiș had been under Ottoman occupation and later under Habsburg administration. During the latter period the settlement had undergone an accentuated development.
