The present study analyzed the distribution routes of the invasive Chinese sleeper  (Perccottus glenii  Dybowski, 1877) and its parasites, focusing on the Carpathian region of Europe. The invasive Chinese sleeper was sampled using beach seines from two rivers in Ukraine, then assessed for parasites. Published data about its parasites in Central and Eastern Europe were analysed and compared to these current data. Six parasite taxa were found in the studied sites, of which just two – the ciliates  Trichodina  spp. and the cestode  Amurotaenia perccotti  – were relatively numerous. All other parasites occurred sporadically in just single specimens. Samples of the invasive Chinese sleeper in Ukraine were infested by primarily just one species, with most individuals entirely lacking parasites. Comprehensive examination of the comparative literature for Chinese sleeper parasitism identified 77 parasitic taxa from the Carpathian region. Three species of parasites likely were introduced to Carpathian region of Europe together with the Chinese sleeper, with all being specialists: the coccidian  Goussia obstinata , the monogenean  Gyrodactylus perccotti , and the cestode  A. perccotti . The occurrence of  A. perccotti  in Transcarpathian Ukraine reveals the Chinese sleeper’s introduction pathway from the Dniester River basin into the Danube River basin. Findings of  G. perccotti  on specimens of the Chinese sleeper from the Dnieper River show dispersal through the Vistula River basin, where this parasite was previously recorded. These data thus support the ‘enemy release hypothesis’, exemplified by low parasite load, in combination with host-parasite co-invasion.
