171 Ophelia is a main belt asteroid, a member of the Themis family of asteroids.
It is large in size and its surface is dark. It probably has a primitive composition, similar to that of the carbonaceous chondrite meteorites.
It was discovered by Alphonse Borrelly on January 13, 1877 and named after the character in Shakespeare's Hamlet.
The discovery of a possible satellite was reported in 1979 based on lightcurve data. However, it has not been confirmed.
Ophelia is also the name of a moon of Uranus.
