The characters of The Jetsons include:
Meet George Jetson...
- Voiced by: George O'Hanlon (1963-1989), Jeff Bergman (1989-present)
George J. Jetson, the patriarch of the Jetson family. He is the husband of Jane and the father of Judy and Elroy Jetson.
- Bumbling Dad: His personality is that of a well-meaning, caring father, but he is often befuddled and stressed out by the problems of both his work and family lives.
- Boss's Unfavorite Employee: He remains Bad Boss Cosmo Spacely's only employee to be visibly and audibly dismissed ("Jet-SSSOOOOOOONNN! You're fired!") constantly, for any damn reason Mr. Spacely could think of. George has also been made the guinea pig for an indestructible outfit (the outfit survived the rigorous tests, George not so much), shipped to Places Worse Than Death (Outer Moongolia, for example) and endured varying amounts of physical abuse from his Bad Boss.
- Butt-Monkey: In addition to getting fired every episode, George is also on the receiving end of a lot of slapstick.
- Catchphrase: "JANE STOP THIS CRAZY THING!"
- "Out! Out! OUT!"
- In the Eighties, he picked up "Ooba-dooba!"
- Crazy Jealous Guy: He hates it when other men flirt with Jane.
- Gag Nose: Has a cartoonishly large nose.
- George Jetson Job Security: The Trope Namer. When it came to Mr. Spacely, George had absolutely zero protection, and when he wasn't fired he lost whatever bonuses he obtained from being part of Spacely's latest scheme just as easily. Spacely threatened to fire George for any reason that he could threaten him for, from arriving late to work up to not voting in favor of Spacely's dog in a canine competition or winning a Family Feud-style game show that had the Jetsons and the Spacelys facing off (thankfully for George and his family, the second prize was exactly what they needed).
- Happily Married: Although he's oogled a few other women, he really does love his wife, Jane.
- Heroes Want Redheads: His wife Jane is a redhead; coincidentally George is one too.
- Jerk with a Heart of Gold: He may be bossy and loud, but he deeply loves his family. Even Astro.
- Overprotective Dad: He's overprotective of Judy because of how boy-crazed she is.
- Vocal Evolution: His voice got higher and goofier in the 80's revival and movie.
His boy, Elroy...
Elroy Jetson, the only son and youngest child of the family.
- The Ace: Good grades, a genius with technology, and he's also quite the athlete.
- The All-American Boy: A futuristic version of the same.
- Child Prodigy: He excels at space science and mathematics at an elementary school educational level, no less. In the '80s episodes, he develops a program to debug R.U.D.I., wins a science fair, develops an electronic dog trainer, and invents a device that can accelerate evolution, temporarily turning Astro into a genius.
- Gadgeteer Genius: He's gifted with technology having built several robots and gadgets throughout the show's run.
- Nice Guy: He is a mild mannered and good child.
- Wise Beyond His Years: He's very intelligent for someone still in elementary school.
Judith "Judy" Angela Jetson is the sixteen-year-old daughter of George and Jane Jetson who acts just like a normal teenage girl only with more futuristic tastes.
- Alliterative Name: Judith "Judy" Jetson.
- Bare Your Midriff: Her default outfit shows off a little bit of the belly.
- Bratty Teenage Daughter: She usually acts much like a typical rebellious American teenage daughter whose interests include clothes, hanging out with boys, and revealing secrets to her diary.
- Fangirl: Judy is very fond of a futuristic rock singer named "Jet Screamer".
- Girly Girl: She enjoys shopping, boys, and fashions.
- Hormone-Addled Teenager: She's obsessed with boys, to the point where George often feels uncomfortable.
- Leitmotif: Represented in the theme song by a wild jazz trumpet solo, courtesy of Pete Candoli.
- Mystical White Hair: She has white hair and is an attractive teenager.
- Smitten Teenage Girl: Judy is this for no boy in particular. Often, the object of her affections will be some famous rock star, whom she inevitably meets and then forgets about by the next episode.
- Strong Family Resemblance : She actually does look like her mother.
Jane, his wife...
- Voiced by: Penny Singleton (1963-1990), Grey DeLisle Griffin (2006-present)
- Absurdly Youthful Mother: She doesn't look any different than 16-year-old Judy. In the first episode it is revealed that she's 33.
- Alliterative Name: Jane Jetson.
- Beware the Nice Ones: Although she is usually pleasant natured, she'll get rather pissed if you push her to her limit.
- Clingy Jealous Girl: She doesn't appreciate George ogling another woman.
- Drives Like Crazy: She has terrible driving skills, turning her driving instructor, a gangster and her husband into nervous wrecks ("Jane's Driving Lesson").
- Graceful Ladies Like Purple: Wears a purple dress and is very feminine.
- Happily Married: She genuinely loves and supports George.
- Housewife: She is a homemaker (although it is Rosie who does most of the work).
- Mama Bear: She is quite protective of her family and she can be angered whenever they are threatened.
- Nice Girl: She's sweet, motherly, and tries to be kind to everyone. Though she has her limits.
- Voiced by: Howard Morris
George's 110-year old grandfather and the great-grandfather of Elroy and Judy.
- Cool Old Guy: He's still an active daredevil at 110 years old, and even fills in as Judy's partner at the father-daughter dance to spare her the embarrassment of dancing with her dad.
- Berserk Button: Don't lay a finger on George or Elroy; he'll make you regret it.
- Dogs Are Dumb: He can talk, but it doesn't mean he's too bright.
- Innocently Insensitive: He does get George hurt through his own stupidity as shown in the ending credits, but he means well.
- Speech-Impaired Animal: "Roh roy, Rorge!" Depending on how you look at it, Astro is either the forerunner of Scooby-Doo in this regard, or a futuristic descendant of the same. Much like Scooby, this characteristic is subtly dropped around the 80s revival, notably during The Jetsons Meet the Flintstones. Though it is brought back for The Movie.
- Talking Animal: Although most of what he says starts with an R.
- Who Names Their Kid "Dude"?: In "Millionaire Astro", J.P. Gottrockets' attorney tells the family that Tralfaz is the real name of the dog the Jetsons call Astro:Astro: "Tralfaz"? Yecch!
Rosie, the Robot Maid
- Voiced by: Jean Vander Pyle (1963-1990), Tress MacNeille (2008-present)
She may be "only nuts & bolts," but she's loved like a member of the family all the same.
- Advertised Extra: In the original run from the 60s she appeared in only two episodes. Not the case in the 80's revival where she regularly appeared.
- Fembot: Definitely female through her voice and Tertiary Sexual Characteristics.
- Robot Maid: Possibly the Trope Codifier.
- Servile Snarker: Usually she makes sarcastic comments.
- Tin-Can Robot: She was introduced by a robot salesperson as an "old-fashioned" model in the very first episode she appeared.
- Token Robot: A Fembot for the titular family.
A little alien first introduced in "Elroy Meets Orbitty" and a pet of the family.
- Amusing Alien: He does wacky things like hang from the ceiling.
- Kaleidoscope Hair: Or fur, rather. His fur changes colour depending on his mood (e.g. yellow for fear and pink for affection).
- Mr Fix It: He can repair electronic devices.
- Pet Baby Wild Animal: He was adopted by Elroy after having just hatched out of the egg he found on an asteroid. A rare example where the animal stays.
- Adaptational Villainy: While he was usually portrayed as a Mean Boss to George in the series, in The Movie he veers into straightforward Corrupt Corporate Executive territory, without almost any of his redeeming qualities of the series.
- Big Bad: While he isn't exactly a bad man, he is often the main antagonist of George in many chapters and plots focused in him. And effectively he is the main antagonist of The Movie.
- Catchphrase: "Jetsoooooooooon!! Youuuuuuuuuuuu're Fiired!"
- Corrupt Corporate Executive: Shows shades of this in the main series. He's greedy and has fired George, at least once an episode. Veers straightly in this territory in The Movie: he is knowingly destroying an alien colony for raw materials...
- George Jetson Job Security: He frequently fires the Trope Namer, only for George to get his job back later.
- Hair-Trigger Temper: His temper goes off once an episode.
- Henpecked Husband: To his wife Stella.
- Jerk with a Heart of Gold: He can be harsh towards his employees, especially George, but he cares for them too.
- Large Ham: Especially when he's about to fire George.
- Mean Boss: The most iconic example in media. He's often like this to George.
- Never My Fault: Mr. Spacely sometimes fires George for incidents that were caused by Spacely himself.
- The Napoleon: For his size, he has a huge temper.
- Tiny Guy, Huge Girl: Mr. Spacely's wife towers over him.
- Vocal Evolution: He sounds almost unrecognisably soft spoken at the start of the original series. Mel Blanc gave him a more gravelly bellow as the series continued, especially in the 80s revival, by which point you'd wonder if Yosemite Sam were one of his ancestors.
- Corrupt Corporate Executive: He is a more straight-up example than Spacely, who is more a Mean Boss than these.
- Eviler Than Thou: Sure Spacely has Jerkass moments, but he does have redeeming qualities unlike Cogswell.
- Expy: He looks hardly any different from Fred Flintstone's boss, Mr. Slate.
- Jerkass: All of Spacely's abrasiveness, with none of the redeeming qualities.
- The Rival: To Cosmo Spacely.
- Shadow Archetype: He doubles on any of Spacely's vices as a businessman.
