A total of 123 species of aculeate Hymenoptera are reported from the Murmansk region based on museum collections, unpublished datasets and previously published records. Collection localities are provided for each species. Erroneous or doubtful records of additional 19 species are discussed. Noteworthy findings include e.g. Ammophila campestris, Bombus consobrinus,B. hyperboreus, Crabro maeklini, Dipogon vechti, Formica suecica, Gorytes neglectus, Osmia cf. disjuncta and O. maritima. The species Ammophila campestris, Bombus veteranus, Crossocerus varus, Formica polyctena, Lindenius albilabris, Megachile analis and Osmia cf. disjuncta have their northernmost known localities in the Murmansk region. We estimate that approximately 100 additional aculeate species could still be found from the area.
