In Greek mythology, Larissa (Ancient Greek: Λάρισσα) was a local nymph from Thessaly. She was described by Pausanias as a daughter of Pelasgus. However, Hellanicus states that the sons of Poseidon and Larissa were Achaios, Phthios, and Pelasgus. Strabo (Geographika, xiv) calls her a daughter of Piasus, a Pelasgian prince.
She was represented on the obverse of common drachms produced by the city of Larissa between 400 BCE and at least 340 BCE, as a three-quarters face with outward flowing hair. This style was copied from the head of Arethusa by Cimon, depicted on Syracusan tetradrachms. According to hoard evidence from Thessaly, this coinage was produced down to c. 320 BCE. Other coins depict Larissa seated, holding a hydria and with a spring nearby, confirming her status as a nymph.
A moon of Neptune was discovered by Harold J. Reitsema, William B. Hubbard, Larry A. Lebofsky and David J. Tholen on May 24, 1981 and later given the name Larissa. Larissa is also designated as "Neptune VII", S/1981 N 1 and "S/1989 N 2".
