Results of the first study of the fauna and ecology of bumblebees (Hymenoptera, Apidae, Latr.) in the northern part of the Yugyd Va National Park are presented. In the field studies of 2012–2023, sixteen bumblebee species from seven subgenera were discovered, which makes up 44% of the fauna of the North-East of European Russia. Most of them have vast ranges and, according to the type of biopreferendum, belong to eurytopic and meadow-forest species. The population structure is similar to that in the lowland part of the northernmost taiga and has a number of differences from that in the southern part of the national park. The highest levels of species diversity and richness are characteristic of floodplain forb meadows and larch forests. Consortial relationships of bumblebees with 75 plant species from 16 families were revealed, including seven plant species from the Red Data Book of the Komi Republic (2019). The most visited by the bumblebees plants include representatives of the families Asteraceae, Apiaceae, Plantaginaceae, Onagraceae, Ericaceae, and Geraniaceae. Based on the data of palynological analysis, as well as on those of the conducted surveys, it can be concluded that the pollination of some plant species by bumblebees is highly efficient.
