The Cassiporé River is a river of Amapá state in north-eastern Brazil.

Cabo Cassiporé is a low promontory about 6 miles (9.7 km) east of the wide entrance to the river. The land from Cabo Orange to the north and Cabo Cassiporé is low and often flooded, with shallow water up to 12 miles (19 km) from the shore.

The Cassiporé river can be navigated by boats drawing under 2 metres (6 ft 7 in) as far as the town of Japa, 24 miles inland. The tidal range at the river mouth is less than 4 metres (13 ft). The Cassipore River run through the most northern part of the Amapá mangroves ecoregion along the bay where it flows into the Atlantic Ocean.
