Jillian Jackson is a teenage party girl and former girlfriend of Garfield Logan. She is noted mostly for her ever-changing hair color (usually pink or blue). Years after Jillian and Gar parted ways, Jillian came back into Gar's life during a period when he was still coping with the betrayal and ultimate death of another former girlfriend, Terra. Jillian helped him through some of his dark times and later attended the wedding of Donna Troy and Terry Long as Gar's date.

However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
