The Canaticú River (pt|Rio Canaticú) is a tributary of the Pará River of the state of Pará, Brazil.
The river is on the island of Marajó to the northwest of Belém in the delta region where the Amazon and Tocantins rivers empty into the Atlantic Ocean.It runs through part of the Terra Grande-Pracuúba Extractive Reserve, a sustainable use conservation unit created in 2006.Access to the Canaticú and the nearby Pracuúba River is difficult during the summer dry season.The communities on these rivers have an açaí palm crop that ripens in the winter, between seasons in other areas, which therefore commands a high price.The Canaticú flows south into the Pará River, which connects the Amazon River to the Tocantins River.
