The Hârtibaciu River (German: Harbach, Hungarian: Hortobágy) is a river in the Transylvania historical region of Romania. It develops in the South Carpathians and flows into the Cibin River, a tributary of the Olt, near Boiţa.
King Géza II of Hungary settled the initial Transylvanian Saxon colonists along the Hârtibaciu, referred to by them as the Harbach. The Saxons established many towns along the river such as Agnita with Kirchenburgen, or fortified churches.
