Chroococcus giganteus is a species of cyanobacteria in the family Chroococcaceae, notable for being among the largest-celled representatives of its genus, as indicated by the specific epithet. While cyanobacterial cells are generally microscopic, there is considerable variation in cell size within the genus Chroococcus, and giganteus refers to its relatively large cell diameter compared to other species in the group. Chroococcus cells are spherical to hemispherical, typically dividing by binary fission to form pairs or groups of two to four cells enclosed within layered mucilaginous sheaths. The photosynthetic pigments in the cells give them a blue-green to olive coloration. Chroococcus giganteus has been documented from freshwater and moist terrestrial habitats in various geographic regions. As a cyanobacterium, it contributes to primary production in its habitat and potentially to nitrogen cycling if it possesses nitrogen-fixing capacity. Taxonomic resolution within the genus Chroococcus remains challenging due to the limited morphological complexity of these organisms and the significant influence of environmental conditions on cell size and sheath development. The species has not been assessed by the IUCN.
