The study of the ectoparasite fauna of the insectivores—<i>Sorex araneus</i>, <i>Sorex minutus</i>, <i>Neomys fodiens</i>, and <i>Neomys anomalus</i> (subfamily Soricinae)—was carried out in three locations in Poland: Białowieża National Park, Kosewo Górne in the Masurian Lake District, and in vicinity of Warsaw. Three species of Ixodidae ticks, eleven species of fleas, and four species of mites from the order Mesostigmata were noted. The most numerous ectoparasites are ticks <i>Ixodes ricinus</i> (larvae), <i>Dermacentor reticulatus</i> (nymphs), and fleas <i>Palaeopsylla soricis</i>, <i>Megabothris walkeri</i>, and <i>Hystrichopsylla orientalis</i>. These species show the highest prevalence and show the highest dominance index. The parasitofauna of <i>S. araneus</i> is much richer in species than other shrew species. The structure and dominance of parasite assemblages differ between locations.
