Ophelia (oe-fee'-lee-a) is a moon of Uranus. It was named after the daughter of Polonius in William Shakespeare's play Hamlet. Ophelia acts as the outer shepherd satellite for Uranus' epsilon ring. Its orbit is within Uranus' synchronous orbit radius, and is therefore slowly decaying due to tidal forces.
It was discovered from the images taken by Voyager 2 on January 20, 1986, and was given the temporary designation S/1986 U 8. It is also designated Uranus VII.
There is also an asteroid called 171 Ophelia.
