    Clusiaceae is a family of Neotropical angiosperms with significant representativeness in Brazil, particularly Clusia L., which includes 80 species within this national territory. Despite this, the group is still poorly studied in Northeastern Brazil, a region that includes Alagoas, a state where Clusia the representatives of this genus compose the phytophysiognomies of the Caatinga biome and Atlantic Forest, especially the last one. They are characterized mainly by their shrubby to arboreal habit, coriaceous leaf blades, presence of exudate, and flowers that, for the most part, offer resin as a floral reward for pollinators. Beyond ecological significance, Clusia has also potential for landscaping. Considering this aspects associated to the scarcity of taxonomic studies in the regional flora, this work consists of a floristic–taxonomic survey of Clusia for the state of Alagoas, Brazil. Collection expeditions were carried out in different regions to cover the biomes represented in Alagoas. Morphological–taxonomic analyses were based on the collection of the Herbarium of the Environmental Institute of the State of Alagoas (MAC), complemented by additional field collections. Six species were recorded: C. dardanoi G. Mariz & Maguire, C. melchiorii Gleason, C. nemorosa G. Mey, C. paralicola G. Mariz, C. rosea Jacq., and C. sellowiana Schltdl. The treatment includes an identification key, morphological descriptions, a list of examined material, data on geographic distribution, preferred environments, reproductive phenophases (flowering and fruiting), photographic images, and comments on the morphological affinities of the species based on morphological characters. The most widely distributed species are C. nemorosa G. Mey, C. paralicola G. Mariz, and C. melchiorii Gleason.
