The Daldykan (Russian: Далдыкан or Долдыкан Doldykan) is a river close to Norilsk in Taymyrsky Dolgano-Nenetsky District, Krasnoyarsk Krai in Russia, a right tributary of the Ambarnaya. It is 29 kilometres (18 mi) long, and has a drainage basin of 98.4 square kilometres (38.0 sq mi).
The Daldykan has been regularly polluted by nickel industry, namely from Nornickel; as a result the river's water has turned red.
