The present study presents new data on the helminths and helminth communities of fish from the freshwater ecosystem of the Luda Yana River as part of the Maritsa River Basin in Bulgaria, Eastern Aegean Water Basin. In connection with this, 32 specimens of Orpheus dace (Squalius orpheus Kottelat & Economidis, 2006) were collected and examined. The specimens were collected in the autumn of 2022 in the vicinity of the Popintsi village, located in the middle section of the Luda Yana River. The helminthological examination was carried out according to standard methods. Invasion with 3 species of helminths was found - one cestode species (Caryophyllaeides fennica (Schneider, 1902) Nybelin, 1922); one acanthocephalan species (Acanthocephalus lucii (Müller, 1776) Lühe, 1911) and one nematode species (Rhabdochona denudata (Dujardin, 1845) Railliet, 1916). Ac. lucii is reported for the first time from Sq. orpheus in Bulgaria.
