Mosses were collected in the municipality of Anajás, on the Marajó Island, in the northen Brazilian state of Pará. This work continues the survey of the Bryophyta flora of this island. Thirty-four species, belonging to 25 genera and 17 families, were identified from the municipality. Calymperaceae and Sematophyllaceae stand out as the families with the greatest number of species (six and five, respectively). The mosses Syrrhopodon leprieurii Mont., Fissidens elegans Brid., Isopterygium subbrevisetum (Hampe) Broth, and Meiothecium boryanum (C. Müll.) Mitt, represent new records for the state of Pará.
