Praxidike (prak-sid'-i-kee, Greek Πραξιδίκη) (Jupiter XXVII) is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2000, and given the temporary designation S/2000 J 7. Praxidike is about 6.8 kilometres in diameter, and orbits Jupiter at an average distance of 20,824 Mm in 613.904 days, at an inclination of 144° to the ecliptic (132° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.1840.
It is named after Praxidike, the Greek goddess of punishment.
Praxidike belongs to the Ananke group, retrograde irregular moons which orbit Jupiter between 19.3 and 22.7 Gm, at inclinations of roughly 150°.
