About
 is a major supporting character of the 1985 Walt Disney Animated Feature The Black Cauldron.

Eilonwy is a princess who had been captured by the Horned King during his search for the Black Cauldron; however, she had free reign over the dungeons of the castle while working out a plan for escape which she springs after Taran is likewise captured by the warlord. Although a sweet and caring girl, Eilonwy is also fiery and can be tempered by not getting the respect for what she is capable of. She is usually followed by a small golden bauble that she uses to light her way through darkness and to scare away any rats.

Although her claims of being a princess were not confirmed in the film, in the original "Chronicles of Prydain" novel series, Eilonwy is confirmed to be a princess and a sorceress-in-training from the island of Llyr.
