The paper provides information on new species of the Poaceae family, alien for the flora of Dagestan and the Eastern Caucasus, identified during field studies and in the analysis of various herbarium collections in 2020-2022. For the flora of the Eastern Caucasus, Echinochloa tzvelevii and Setaria adhaerens are indicated for the first time, and the presence of feral cultivated species in the flora of Dagestan is confirmed: Avena sativa, Lolium multiflorum, Sorghum drummondii, Sorghum technicum . For the first time for the flora of Dagestan, the quarantine species Cenchrus longispinus is presented. For each species, a brief description of the location is given, information on population status, phenophase, etc. is presented. In addition, an invasive status was assigned to each species, according to the criteria and guidelines used in the work on the regional "Black Books". Sorghum technicum and Cenchrus longispinus have a higher invasive potential (status 2), while the remaining 5 species ( Avena sativa, Echinochloa tzvelevii, Lolium multiflorum, Sorghum drummondii, Setaria adhaerens ) occur in disturbed and segetal communities (status 3).
