Ilha Tupinambarana used to be the name of a fluvial island bordered by Amazon rivers (Amazon, Madeira, Sucunduri, and Abacaxis) in Amazonas, Brazil. Today, it has been split into four completely separate parts by natural channels just like the one which isolates it from the mainland of America. So it is no longer one island, but indeed four islands. The total area of these islands sums up to 11,850 km², making Ilha Tupinambarana the second largest fluvial group of islands in the world after Bananal Island.

The group of islands is largely forested, and is only accessible by river or by air. It has a small mountain range, and is home to the city of Parintins, known for the Parintins Folklore Festival. There are also remains of a village constructed in the 1930s by Japanese settlers hoping to cultivate jute.
