The article provides an overview of the family Mimosaceae (Fabaceae s. l.) in the flora of the emirate of Fujairah, located in the mountainous northwestern part of the Arab Emirates (UAE). The flora of the emirate is studied by the authors for a number of years, from 2017 to 2022. Based on field studies, surveys of irrigated gardens, public parks, urban plantations and nurseries, herbarium materials and literature data, the list of species was compiled. As a result, the article provides an overview of wild and cultivated species (native and introduced) that are found in nature or cultivated in open ground conditions in the emirate of Fujairah. Genera and species are arranged in alphabetical order, with separate wild and feral species and cultivated non-wild species. We also took into account our data on species found only in plant nurseries. The list contains 14 species from 8 genera. Indigenous and alien, cultivated (ergasiophytes) and running wild from culture (ergasiophygophytes) or spreading independently (xenophytes) are indicated. Leucaena leucocephala (Lam.) de Wit is proposed as a new alien species for Fujairah, a number of species – Acacia auriculiformis A. Gunn ex Benth., A. stenophylla Benth. and Mimosa pudica L. for the first time as a wild or alien species for Fujairah, the United Arab Emirates and Arabia as a whole.
