Praxidike /prækˈsɪdək/, also known as Jupiter XXVII, is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2000,[7][1] and given the temporary designation S/2000 J 7.

It was named in August 2003 after Praxidike,[8] the Greek goddess of punishment.
