The Körös (in Hungarian pronounced as /ˈkørøʃ/) or Criș (in Romanian; Moldavian; Moldovan pronounced as /'kriʃ/) (German: Kreisch) is a river in eastern Hungary and western Romania. Its length is 128.6km (79.9miles) from the confluence of its two source rivers Fehér-Körös (Crișul Alb) and Fekete-Körös (Crișul Negru) to its outflow into the Tisza. Its drainage basin area is 27537km2.[3] It has three source rivers, all with their origin in the Apuseni Mountains in Transylvania, Romania: Crișul Alb (Fehér-Körös), Crișul Negru (Fekete-Körös) and Crișul Repede (Sebes-Körös). The confluence of the rivers Fehér-Körös (Crișul Alb) and Fekete-Körös (Crișul Negru) is near the town Gyula. The Körös downstream from Gyula is also called the Kettős-Körös (Hungarian for "double Körös"). 37.3 km further downstream, near Gyomaendrőd, the Sebes-Körös (Crișul Repede) joins the Körös/Criș. The section downstream from Gyomaendrőd is also called the Hármas-Körös (Hungarian for "triple Körös"). The Körös flows into the Tisza River near Csongrád.
It was known in antiquity as the "Chrysus", Crisus, Crisia, Grisia, or Gerasus.
