In Greek mythology, Eurryroe (Ancient Greek: Εùρυῥῤόης) was the daughter of the Egyptian river-god Nilus, thus she can be considered as a naiad. According to Hippostratus, Eurryroe was said to be the mother alone of the 50 sons of King Aegyptus of Egypt.^[1] Her sister Europa, also bore the Libyan king Danaus's 50 daughters.^[2] Otherwise, Aegyptus's children were bore to different mothers including Argyphia, Tyria, the naiad Caliadne, Gorgo and Hephaestine.^[3]
