The Torysa (German Törz, Hungarian Tarca) is a 129 km long river in eastern Slovakia.
It is the longest tributary of the Hornád, which drains to the Danube via the Sajó and the Tisza.
The river rises five kilometers northwest of Torysky at the foot of the 1224 m Javorina (German knee bender), an elevation in the Leutschau Mountains (Levočské vrchy).
The partly tortuous upper course initially flows towards the east. From Lipany the valley widens and turns to the south-east. On the way from Lipany to Sabinov, the Torysa takes in many small mountain streams from the northern Čergov mountain range and the southern Bachureň highlands. The stretch of the river from Sabinov via Veľký Šariš to Prešov is characterized by gentler slopes, the valley is used intensively for agriculture and the forest cover is receding.
In Prešov, the third largest Slovak city, the Torysa receives the Sekčov River coming from the north and from then on flows south to the mouth. Near the municipality of Obišovce, the Hornád and Torysa rivers converge at 2500 m, but diverge again and flow parallel to each other for 25 kilometers before the Torysa flows into the Hornád south of the Nižná Hutka municipality. The last 40 kilometers of the now meandering course of the Torysa river are already in a flat area, which opens to the Košická kotlina basin. The catchment area of the Torysa is 1349 km² (Wikipedia).
