Cordelia är en av Uranus månar. Den upptäcktes 1986 vid passagen av den amerikanska rymdsonden Voyager 2, och fick den tillfälliga beteckningen S/1986 U 7. Den är också betecknad Uranus VI.

Cordelia är uppkallad efter kungens yngsta dotter i William Shakespeares pjäs Kung Lear.

Man vet knappt någonting annat än om dess omloppsbana ^[1], dess radie på 21 km^[2] och den geometriska albedon på 0,08^[3]. På bilder tagna av Voyager 2 ser Cordelia ut att vara avlång till formen, den längre axeln pekar mot Uranus. Axelvärdena av Cordelias form är 0,7 ± 0,2.^[2]

Cordelia agerar som en inre herdemåne till Uranus Epsilonring.^[5]
