Judy Jetson is a main character in "The Jetsons". She is the daughter of Jane Jetson and George Jetson. She is 15 years old. She was voiced by Janet Waldo and Jodie Resther.

Judy is the daughter of her Mother Jane Jetson & her Father George Jetson. She is a typical teenage girl. She is beautiful with the boys, rock stars, clothes, and loves to hang out with her best friends at Orbit High School. Judy can usually be found goggling at posters and listening to the radio in her room, but she does make time to play with her little brother Elroy Jetson. She enjoys the many gadgets at her grasp like controllable zero-gravity switches made for accomplishing popular dance moves. She also gives a summary of how her day went including her problems to a floating robotic diary, appropriately named "DiDi".

Judy is also very fond of a futuristic rock singer named Jet Screamer. George Jetson at first despised him until Judy won a date with the heartthrob singer in a song-writing contest. Judy won when George Jetson replaced her original song with her younger brother Elroy Jetson's secret code. George Jetson came along to try to stop the date but failed and wound up as the drummer for the song and soon took a liking to Jet Screamer and his music.
