Cressida (kres'-i-da) is a moon of Uranus. It was named after the Trojan daughter of Calchas, a tragic heroine who appears in William Shakespeare's play Troilus and Cressida (as well as in tales by Geoffrey Chaucer and others). Other than its size and orbit, virtually nothing is known about it.

It was discovered from the images taken by Voyager 2 on 1986-01-09, and was given the temporary designation S/1986 U 3. It is also designated Uranus IX.

There is also an asteroid called 548 Kressida.
