Praxidike or Jupiter XXVII, is a non-spherical moon of Jupiter. It was found by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2000,^[1]^[2] and given the designation S/2000 J 7.

Praxidike orbits Jupiter at an average distance of 20,824,000 km in 613.904 days, at an inclination of 144° to the ecliptic (143° to Jupiter's equator), with an orbital eccentricity of 0.1840.

It was named in August 2003 after Praxidike,^[3] the Greek goddess of punishment.

Praxidike belongs to the Ananke group, believed to be the remnants of a break-up of a captured asteroid.^[4]^[5] With an estimated diameter of 7 km, Praxidike is the second biggest member of the group after Ananke itself (assumed albedo of 0.04)^[6]

The moon appears grey similar to C-type asteroids.^[7]
