The Kollaa (Russian: Колласйоки, Finnish: Kollaanjoki or Kollasjoki) is a 76-kilometre (47 mi) long river in the Republic of Karelia, Russia. It starts from Lake Kollasjärvi in the Suoyarvsky District and flows to Lake Tulmozero (Finnish: Tulemajärvi) in the Pryazhinsky District.
Before World War II, the source of the river was a part of the Finnish municipality Suistamo and it flowed further through Suojärvi to Tulemajärvi on the Russian side.
