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. Her sister Europa, also bore the Libyan king Danaus's 50 daughters. Otherwise, Aegyptus's children were bore to different mothers including Argyphia, Tyria, the naiad Caliadne, Gorgo and Hephaestine.
