In Greek mythology, Arsinoe sometimes spelled Arsinoë, (Ancient Greek: Ἀρσινόη derived from arsis "to rise, to lift" and nous "mind, intellect" ), was the name of the following individuals.
- Arsinoe, one of the Nysiads (Dodonides), nurses of the infant Dionysus in Mount Nysa.
- Arsinoe, daughter of Leucippus and possibly Philodice. She was also the sister of Hilaeira and Phoebe, who were abducted by the Dioscuri. By the god Apollo, Arsinoe bore Asclepius, 'leader of men' and Eriopis 'with the lovely hair'. Otherwise, the mother of Asclepius was called Coronis, daughter of Phlegyas because it is said that Asclepius being the son of Arsinoe, was a fiction invented by Hesiod, or by one of Hesiod's interpolators, just to please the Messenians. At Sparta she had a sanctuary and was worshipped as a heroine.
- Arsinoe, one of the Minyades, according to Plutarch. These daughter of Minyas were struck with madness and having conceived a greedy appetite for man's flesh, cast lots accordingly for their children to see who they were going to eat. Whereupon it fell to Leucippe's lot to produce her son Hippasus to be cut in pieces.
- Arsinoe or Alphesiboea, daughter of Phegeus, king of Psophis in Arcadia and sister of Pronous and Agenor. She was the wife of Alcmaeon, leader of the Epigoni by whom she bore a son, Clytius.

There they gave her as a slave to Agapenor, falsely accusing her of her husband's murder. Eventually, retribution came when the sons of Alcmaeon, Amphoterus and Acarnan slew their father's murderers and also Phegeus and his wife.
- Arsinoe, nurse of Orestes who saved him from the hands of his mother Clytemnestra, and carried him to the aged Strophius, the father of Pylades. Other traditions called this nurse Laodameia.
- Arsinoe, daughter of King Nicocreon of Salamis in Cyprus (descendant of Teucer, son of Telamon). She was loved by Arceophon who wooed her, but the maiden's father refused to give his daughter to Arceophon because of the latter's Phoenician descent. Arceophon was upset and began to come to Arsinoe's house by night, hoping to win her heart, but in vain. He then tried to bribe Arsinoe's nurse so that she might arrange for them to meet, but Arsinoe reported this to her parents, who cut off the nurse's tongue, nose and fingers and drove her out of their house.
