The Cuyahoga River (see § Pronunciation) is a river located in Northeast Ohio that bisects the City of Cleveland and feeds into Lake Erie.

As Cleveland emerged as a major manufacturing center, the river became heavily affected by industrial pollution, so much so that it caught fire at least 14 times. When it did so on June 22, 1969, news coverage of the event helped to spur the American environmental movement. For many Americans, the Cuyahoga's burning helped connect urban decay with the environmental crisis at the time in many American cities. Since then, the river has been extensively cleaned up through the efforts of Cleveland's city government and the Ohio Environmental Protection Agency (OEPA). In 2019, the American Rivers conservation association named the Cuyahoga "River of the Year" in honor of "50 years of environmental resurgence".

In 2025 the river between the Gorge Dam and the mouth was designated a National Water Trail, a type of National Recreation Trail.
