The Rinža (German: Rinse, Rinnse) is a river of Slovenia. It is 14 kilometres (8.7 mi) long and flows through Kočevje. It is the main watercourse of the Kočevje Polje and it is a losing stream. A few kilometers downstream of Kočevje, it goes subterranean. It emerges again as the Bilpa, a tributary of the Kolpa.
