Hermippe or Jupiter XXX, is a moon of Jupiter. It was found by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2001, and given the designation S/2001 J 3.[1][2]

Hermippe is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 21,182,000 km in 629.809 days, at an orbital inclination of 151° to the ecliptic (149° to Jupiter's equator), with an eccentricity of 0.2290.

It was named in August 2003 by the IAU, after Hermippe, a lover of Zeus (Jupiter).[3]

Hermippe belongs to the Ananke group, retrograde non-spherical moons which orbit Jupiter between 19,300,000 and 22,700,000 km, at inclinations of about 150°.
