The '''Raging Neisse'''<ref>Dodge, Lt Col Theodore Ayrault. ''Napoleon: A History of the Art of War. Vol. IV'', 2014</ref>{{efn|''Neisse'' is pronounced "nicer".}} ({{langx|pl|Nysa Szalona}}, {{Langx|de|Wütende Neiße}} or ''Jauersche Neiße'') is a river in Poland. It has a length of about {{convert|51|km}} and flows into the Kaczawa, which in turn flows into the Oder. Its largest tributary is the Little Neisse.

The Raging Neisse rises at a height of {{convert|600|m}} on the western side of a mountain called the Kokosz on the Wałbrzych Heights. It flows down through the lowlands among the foothills of the Sudetes and the heights of Chojnów, through the towns of Bolków and Jawor. It then merges with the Kaczawa at a height of {{convert|141|m}} not far from Jawor near the village of Dunino.

The fact that the Neisse runs through hilly terrain for almost its entire length results in that during heavy rainfall, the water level in the river can suddenly rise up even to 2 meters , hence its name – the Raging Neisse

== Napoleonic Wars == The river became famous as a result of the Battle of Katzbach when fleeing French troops being pursued by Marschall Blücher were driven into the Katzbach and Raging Neisse rivers which were swollen as the result of a thunderstorm.{{sfn|Rose|2018|p=241}}
