Megaclite Template:IPAc-en, also known as Template:Nowrap, 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 Template:Nowrap.<ref>IAUC 7555: Satellites of Jupiter Template:Webarchive 2001 January 5 (discovery)</ref><ref name="MPEC-2001-A29">MPEC 2001-A29: S/2000 J 7, S/2000 J 8, S/2000 J 9, S/2000 J 10, S/2000 J 11 2001 January 15 (discovery and ephemeris)</ref><ref>MPEC 2001-T59: S/2000 J 8, S/2000 J 9, S/2000 J 10 2001 October 15 (revised ephemeris)</ref>

Megaclite is about 6 kilometres in diameter, and orbits Jupiter at an average distance of 24,687,000 kilometers in 747.09 days, at an inclination of 150° to the ecliptic (148° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.308.

It was named in October 2002 after Megaclite, mother by Zeus (Jupiter) of Thebe and Locrus in Greek mythology. It was initially erroneously named Magaclite, which was corrected in November 2002.<ref>IAUC 7998: Satellites of Jupiter 2002 October 22 (naming the moon "Magaclite")</ref><ref>IAUC 8023: Satellites of Jupiter 2002 November 29 (correcting the name)</ref> Despite this correction, some earlier research still referred to the moon as Magaclite.<ref name="Grav2003"></ref>

It belongs to the Pasiphae group, irregular retrograde moons orbiting Jupiter at distances ranging between 22.8 and 24.7 Gm, and with inclinations ranging between 144.5° and 158.3°. However, while Pasiphae belongs to the grey color class (V=17.22 B−V=0.74, V−R=0.38), Megaclite falls under the light red color class (V=22.07 B−V=0.94, V−R=0.41), similarly to Callirrhoe and Sinope.<ref name="Grav2003">Template:Cite journal</ref>
