The main island of the archipelago also has the name of Marajó, having about 42,000 km² of area, considered, due to its size, as the largest coastal island in Brazil, extending from the mouth of the Amazon River, between the Line of the Equator and the parallel 1.55º south latitude and, in the E/W direction between the meridians 47º and 53º west longitude, until the Atlantic Ocean.

The aquatic and forming limits of the archipelago are: the Atlantic Ocean (north); the Marajó Bay (east); the Pará River estuary complex (south), and; the Amazon delta (west).
