The paper presents data on the findings of 18 alien species in the city of Lugansk. Based on our own photographs available from Plantarium and iNaturalist websites, 12 species of adventive plants are recorded for the first time for the flora of Donbass, and 6 ones for the flora of the Lugansk People’s Republic. Information is given on locations, nature of habitats and abundancy of identified populations of alien plants, an approximate assessment of the degree of their naturalization and invasive potential being given. According to the degree of naturalization, most of them are epecophytes (eight species), five are colonophytes, three are phanerophytes and two are agriophytes. The results obtained are useful for compiling regional floristic reports and research on the species composition, distribution, and dynamics of adventive species.
