The characters from Confessions of Georgia Nicolson
- Adaptational Nice Guy: Georgia's cynicism and Bratty Teenage Daughter tendencies are very much toned down in the movie, and she's a much more tolerant and normal girl than her book counterpart (not nearly as funny though). It's very evident in her relationship with her parents: in the film she's close to them, while in the books she's repulsed by both, especially her father.
- Anti-Role Model: Even readers in the book's age demographic have found her a complete brat (a lovable brat, but still a brat).
- Book Dumb: Not an excellent student, but she's quite good with foreign languages in and PE (tennis, hockey)
- Bratty Teenage Daughter: She's a total Drama Queen, talks endlessly on the phone with her friends (mostly about boys or makeup), always complains about her parents and claims they are too old and stupid to understand her real problems.
- Brilliant, but Lazy: Georgia hates school and homework, but she is actually quite bright when she's willing to put in the work.
- Characterization Marches On: In the first book, she wishes she weren't so flat-chested. For the rest of the series, her D-Cup Distress is a prominent character trait. It's possible this is a case of Be Careful What You Wish For combined with Truth in Television; many teenage girls hope for a larger bust, only to get one and realize it's not all it's cracked up to be.
- Cloudcuckoolander: She's hilariously silly and a lot of her arguments make no sense to anyone except her.
- Cool Big Sis: For all her faults, Georgia genuinely loves her little sister and the feeling is mutual.
- D-Cup Distress: She apparently has a rather large bust for her age, but she's often more embarrassed and awkward about it than proud.
- Deadpan Snarker: In spades. The books should be renamed "Georgia Nicolson's snarky confessions". She's the epitome of the First-Person Smartass narrator, and it's the main source of humor of the books. Sadly this trait is almost completely absent in the movie.
- Drama Queen: The typical selfish Wangsty overdramatic Bratty Teenage Daughter.
- Dude Magnet: Robbie, Masimo, Dave the Laugh, Peter Dyer, Mark "Big Gob", her cousin James, her younger neighbor Oscar, the French guy who offers her a rose during a field trip...In short, she basically attracts every guy except the ones who are already paired with her friends.
- Everyone Has Standards: Georgia is a self-centered brat and can be cruel, but she's not heartless. She finds the Bummer Twins' torment of Pamela Green to be excessively cruel, and actually stands up for her a couple times. She also does genuinely want her friends to be happy, and dotes on her pet cat and little sister.
- First-Person Smartass: Georgia as the snarky first-person narrator. She describes all the events in a snarky tone.
- Friend with Benefits: With Dave, but kiss only. While she's still interested in/dating Robbie and/or Masimo.
- Fun with Foreign Languages: Georgia speaks almost-fluent French, and she takes German.
- Girly Girl with a Tomboy Streak: She's boy-crazy, and loves makeup and fashionable clothing. She's also a fantastic field hockey player, with a knack for practical jokes.
- Gratuitous French: And, less frequently, Gratuitous German. She just loves to have Fun with Foreign Languages.
- Hidden Depths: You'd never guess it from how self-centered, boy-crazy, and lazy she is, but Georgia is no dummy. And, as detailed in Lovable Alpha Bitch, she does have a kinder side every now and then.
- High School Hustler: She is a rare female example, with her schemes at school and rebellious attitude towards teachers and authority figures.
- Hollywood Dateless: Played straight in the first two books, then it kinda becomes the parody of this trope, with Georgia still complaining about her love life, despite having plenty of boys and love interests.
- Hormone-Addled Teenager: Just like all her friends, she spends much time lusting after cute boys.
- Hypocritical Humor: Again, all the time. When Georgia is annoyed by someone else's flaws, she is often guilty of the same things too. She seems aware of it though, and even makes jokes about it.
- It's All About Me: Georgia seems to care about three things: herself, her looks and cute boys.
- Jerk with a Heart of Gold: Though she's incredibly rude, she can be nice when she wants to be. As Jerkass-ish as she can get, Georgia's Pet the Dog moments make you realize that she really is an okay girl.
- Kindhearted Cat Lover: Angus is one of her primary Morality Pets; for her many faults, Georgia absolutely dotes on that cat.
- Lovable Alpha Bitch: Despite her attitude and shallowness, she's really not that bad. Even if she usually looks down on her unpopular schoolmate Pamela Green, Georgia defends her from the bullies Bummer Twins, and when they are finally expelled, it is because she (along with her friends) told the school authorities that they were the shoplifters, instead of P. Green, who they had initially framed.
- Love Makes You Dumb: Often she acts this way when around a boy. See her interactions with Robbie, where she tends to make a fool of herself and is often unable to make a coherent speech.
- Malaproper: Georgia has... her own unique approach with the English language. She likes to make up her own words ("I must tread a fine line between glaciosity and friendlinosity").
- My God, What Have I Done?: She tries to ignore it and claim she's fine, but it's obvious she does feel really guilty about using Dave to make Robbie jealous in the second book. She even dumps him (and tells him why) because she realizes he's a good guy who doesn't deserve to be led on.Georgia: I am a horrible person. I have dumped Dave. I had to.
- The Nicknamer: She gives nicknames to almost everyone, especially her teachers, Ms. "Hawkeye" Heaton, "Gorgey" Henry, Miss "Slim" Simpson, etc.
- No Sympathy: Usually unsympathetic towards most people around her and generally doesn't care about the other's feelings. Occasionally she gets Pet the Dog moments.
- Obfuscating Stupidity: She may act like a shallow, silly Cloudcuckoolander and sometimes she makes a fool of herself, but she's obviously not stupid.
- Oblivious to Love: Georgia is oblivious to Dave's feelings for her, dismissing them as just him being a nice friend.
- The Prankster: She likes to plays all kinds of childish pranks, especially her teachers, to drive them crazy.
- Single Girl Seeks Most Popular Guy: Robbie and Masimo. She is not content with a normal boy. No, she must have the lead singer of the hottest local band.
- Small Name, Big Ego: Depending on the situations and Rule of Funny. At times she acts ridiculously overconfident, other times she goes into a state of self-deprecating humor.
- Tsundere: The harsh Type, surprisingly not to her boyfriends, but to her friend Jas, in a strange kind of Vitriolic Best Buds and Les Yay way. She always insults and belittles her, but sometimes the insults are accompanied by lines like "I still love you, you are my best friend".
- Unreliable Narrator: The book is entirely from Georgia's point of view, so a lot of things she says are rather... questionable.
- Unsympathetic Comedy Protagonist: Very much so. She's loved by fans for being humorous, sarcastic, lovable and entertaining. She also happens to be vain, selfish, shallow, idiotic, whiny, petty, and rude.
- Vitriolic Best Buds: With Jas. They insult each other a lot and fight in almost every book...they are still best friends.
- Adaptational Nice Guy: Most of her annoying traits, that drive Georgia mad in the books, are toned down in the movie.
- Beta Couple: Jas and Tom are a stable couple for most of the series, in contrast to Georgia's endless love triangles.
- Bitch in Sheep's Clothing: She likes to thinks of herself as a reasonable "good girl", but she's actually very bitchy, judgmental and hypocritical.
- Bumbling Sidekick: In Georgia's eyes. Jas always follows Georgia who constantly pushes her around and tell her who is annoying, useless and can't do anything right.
- Brutal Honesty: Sometimes she annoys Georgia by telling exactly what she thinks, even when she shouldn't. When Georgia messes up, Jas only makes her feel worse.
- Butt-Monkey: Despite being her best friend, she gets much abuse from Georgia, although some of it is quite justified as she can be very annoying.
- Cannot Keep a Secret: She's "Radio Jas", after all. At some point she even tells her boyfriend Tom about Georgia's very personal problems.
- Cloudcuckoolander's Minder: Occasionally, she tries to be the mature voice of reason for Georgia (much to the latter's dismay), even though Jas has plenty of Cloudcuckoolander moments of her own.
- Deuteragonist: She's the one who gets more focus and development, after the title character.
- The Ditz: She definitely has her moments of ditziness, and she's often prone to Comically Missing the Point when she's talking with Georgia.
- Innocently Insensitive: Due to her bluntness and ditziness, she tends to be unintentionally insensitive to Georgia's feelings and problems.
- It's All About Me: Whether she realises it or not, she tends to think more about her own problems and her relationship with Tom, rather than worrying about Georgia. Georgia is Not So Different though.
- Literal-Minded: Very often when she doesn't understand Georgia's speeches and hyperboles, and takes them literally.
- Nature Lover: Along with her boyfriend Tom, they often go into the woods together, which Georgia finds ridiculous.
- Only One Name: She's only called Jas and her last name is never revealed.
- Sickeningly Sweethearts: With Tom. They even give secret nicknames to each other.
- Single-Target Sexuality: Tom is the only guy she has ever been interested in.
- Vitriolic Best Buds: With Georgia. They insult each other a lot and fight in almost every book...they are still best friends.
- Beta Couple: With Sven. They are a stable couple for most of the series, in contrast to Georgia's endless love triangles.
- Cloudcuckoolander: Easily one of the nuttiest characters in the books, along with her boyfriend Sven. Even Georgia is sometimes confused by Rosie's nonsensical thoughts.
- Genki Girl: She's well known for being bubbly and funny, has a lot of energy, and is the most eager to join in Georgia's wild antics.
- The Ditherer: She's also known as the "Dither Queen". She's often often unable to make a decision, changing her mind all the time, especially when she's talking about Dave.
- The Ditz: She becomes dumber after being paired with Dave. In the movie, she's also the most clueless of the group.
- Love Makes You Dumb: She seemed quite normal until she took an interest in Dave the Laugh. Her interactions with Dave makes her seem a borderline stuttering fool.
- Pair the Spares: At the end of Book 2 when Georgia and Robbie get back together, she hooks up with Dave, for no reason other than this trope. Eventually subverted since Dave was such an Ensemble Dark Horse that he ends up being Georgia's true love.
- Token Minority: In the movie she's played by an Indian girl, and is the only major non-white character.
- Adapted Out: Her character is not even referred to in the movie.
- Beta Couple: With Rollo, from book 3 onwards. A secondary couple in contrast to Georgia's endless love triangles.
- Flat Character: She is in every book as one of Georgia's best friends, but gets less focus and lines than the others and we barely know anything about her.
- The Generic Girl: Out of Georgia's friends, she's the one who gets the least focus and defining characteristics.
- Those Two Girls: In the first book with Ellen, Georgia often mentions them together as the other two friends she hangs out with, besides Jas (she will mention Rosie later). She will become this with Mabs in later books, as the two generic members of the group.
- The Bus Came Back: He goes to New Zealand for a year, but comes back to England in later books.
- Chick Magnet: The lead singer of a local band, with plenty of fangirls.
- In-Series Nickname: Sex God, the Guitar Plucker.
- Nice Guy: Both books and movie. One of the few friendly, levelheaded characters in the series.
- Only Sane Man: At least, one of the closest characters to this. He seems a pretty average normal guy with common sense, while Georgia and everyone else around him is absolutely eccentric.
- Savvy Guy, Energetic Girl: Savvy Guy to Georgia's Energetic Girl. He's levelheaded and serious, while she's zany and energetic.
- Tall, Dark, and Handsome: Not as tall as Sven, obviously, but Georgia describes him as such and falls for him at first sight. Also played straight in the movie where he's portrayed by Aaron Johnson.
Dave the Laugh
- Class Clown: He likes to make other people laugh. At some point, he even literally wears a red clown nose.
- Cloudcuckoolander: Not to the extreme, compared to other characters, but his random humor is one of the things Georgia likes about him. He's a goofball who usually doesn't take things seriously.
- Demoted to Extra: In the movie, where he is just a Romantic False Lead.
- Dogged Nice Guy: Even after she dumps him, Dave remains a loyal friend with benefits... to Georgia, but it's obvious he still has feelings for her and they actually get together at the end.
- Friends with Benefits: With Georgia, and all their "accidental snogs".
- Fun Personified: Hence his nickname. He likes to have fun with his friends and you are never bored around him.
- Hormone-Addled Teenager: He admits to Georgia that he is this, when he becomes her "Horn advisor".
- In-Series Nickname: The "Laugh".
- I Want My Beloved to Be Happy: To Georgia. While he's still in love with her but believes she doesn't feel the same, Dave is always sweet and loyal to her and even helps Georgia with her love life and Masimo.
- Jerk with a Heart of Gold: He's a prankster and is full of himself (especially with his skills with girls), but he genuinely cares about Georgia.
- Likes Older Women: He apparently fancies Georgia's mum.
- Only One Name: His last name is never revealed.
- Romantic Runner-Up: Georgia's main love interests are Robbie and Masimo, while Dave is treated as the third wheel. But in the end he gets the girl.
- Second Love: Sort of. Not considering Georgia's first two "boyfriends" Peter Dyer and Mark "Big Gob", neither or whom she was serious about, Georgia's real first love is Robbie, and Dave can be considered the second (though Dave was initially just a Red Herring and Romantic False Lead, but he ends up being one of the most important men in her life).
- Third-Option Love Interest: Throughout most of the novel when Georgia is chasing after either Robbie or Masimo, but snogging him on the side.
- Your Cheating Heart: His "accidental snogging" with Georgia when he's dating other girls.
- Will They or Won't They?: When Dave starts to be featured more prominently in the series, we start to realise that he and Georgia may or may not be the Official Couple.
- Chick Magnet: Like Robbie, he seems to have a lot of girls gawking at him.
- Crazy Jealous Guy: A bit. Who gets the hump over their girlfriend doing the twist with a matey-mate?
- In-Series Nickname: "Luuurve God" and "Italian Stallion"
- Suspiciously Similar Substitute: To Robbie. He replaces him as the singer of Stiff Dylans, as well as Georgia's Love Interest.
- Beta Couple: With Jas, for most of the series. They are a stable couple for most of the series, in contrast to Georgia's endless love triangles.
- Nature Lover: Along with his girlfriend. They both love nature, and spend a lot of time in the forest.
- Nice Guy: He appears to be very friendly to both Jas and Georgia.
- Satellite Love Interest: Has no purpose in the story other than being Jas's boyfriend.
- Adapted Out: Non even mentioned in the movie.
- Beta Couple: With Rosie, for most of the series. They are a stable couple for most of the series, in contrast to Georgia's endless love triangles.
- Cloudcuckoolander: All his brief appearances are random. He never has a single line or moment that makes sense. He obviously gets along with Rosie, who is incredibly kooky herself.
- Funny Foreigner: He's probably from Sweden, and very insane and eccentric.
- Huge Guy, Tiny Girl: Rosie is not that short, but Sven is a giant.
- Non-Specifically Foreign: Not even Rosie is quite sure where he is from.
- Satellite Love Interest: He exists to be Rosie's boyfriend.
Mark "Big Gob"
- Jerkass: He's a delinquent, and probably the worst of Georgia's boyfriends. He treated her quite poorly.
Peter Dyer "Whelk Boy"
- Pair the Spares: Movie only, when he got paired up with Rosie.
- Beta Couple: With Jools, book 3 onwards. They are one of the secondary couples, in contrast to Georgia's endless love triangles.
Mr. Bob Nicolson a.k.a. Vati
- Adaptational Nice Guy: Much more pleasant in the movie than in the books. In the movie he's also very close to Georgia in stark contrast to his book counterpart.
- Amazingly Embarrassing Parents: Georgia hates him, and is disgusted and embarrassed by everything related to her father.
- Bumbling Dad: He's terrible at home maintenance, doesn't know how to act around his Bratty Teenage Daughter and his behaviour is often ridiculous. According to Georgia, he's useless and incompetent at pretty much everything.
- Butt-Monkey: Sometimes, as a result of Georgia's antics. She often pranks him and makes fun of him
- Hair-Trigger Temper: He has quite a temper, yells often, and gets angry at Georgia more often than his wife. But at the same time, you really can't blame him when Georgia provokes him.
- In-Series Nickname: Since the first book Georgia decides to call him "Vati", which is short for "Vater" ("father" in German).
- No Sense of Humor: According to Georgia, at least, who expects him to laugh when she insults him.
- Parental Obliviousness: He and his wife don't know much about Georgia's life. He's always clueless about what his daughter is thinking and doing, and Georgia would never talk about his life with him.
Mrs. Connie Nicolson a.k.a. Mutti
- Age-Inappropriate Dress: Georgia's mutti dresses like a teenage prostitute.
- Amazingly Embarrassing Parents: Not as much as Vati, but she's still prone to embarrass Georgia a lot. Played straight also in the movie.
- Extreme Doormat: She's the most permissive parent compared to her husband, and it's the reason why Georgia tolerates her more than she tolerates her father.
- Good Parents: Georgia doesn't think much of her mother, but there are a few bonding moments between the two, and "Mutti" clearly loves her daughter.
- In-Series Nickname: Since the first book Georgia decides to call her "Mutti" which is short for "Mutter" ("mother" in German).
- Parental Obliviousness: She usually doesn't know much about Georgia's life. Except for the rare times they talk (when Georgia is not snarking her, insulting her or being bratty).
- Pushover Parents: She usually lets Georgia get away with everything.
- Stacy's Mom: There's a lot of Gag Boobs when Georgia's mom is mentioned, and Dave the Laugh finds her attractive.
Liberty "Libby" Nicolson
- Annoying Younger Sibling: Zig-Zagged. In spite of what a pain she can be at times, Georgia is quite fond of her.
- Baby Talk: She speaks only in toddler-gibberish.
- Bratty Half-Pint: She's quite bossy and aggressive, and often uses violence to get her way. Though more innocent than most examples, since she's only 3 and a Cloudcuckoolander.
- Cloudcuckoolander: Her behaviour is downright weird even for a 3-year-old child. She should be about 5 by the end of the series, but she didn't change much. She still uses a pushchair and her social skills only extend to shouting embarrassing things at passersby and cheerfully torturing her male "fwends" at nursery school with make-up and garden implements.
- Creepy Child: Sort of. Her character was all about Toilet Humour and Troubling Unchildlike Behaviour. Even Georgia sometimes is scared of her and finds her behavior disturbing.
- Girls Love Stuffed Animals: She loves to sleep in Georgia's bed, always along with all her stuffed animals and Barbies.
- Morality Pet: For Georgia. Even at her most selfish, Georgia always treats her little sister with kindness and love.
- Troubling Unchildlike Behaviour: She's prone to violence, and tortures little boys at her nursery school.
- Cats Are Mean: A big, wild, insane and violent cat. He intimidates dogs, among other things.
- Cool Cat: Georgia finds him cool because he's brave, strong, and can scare other animals away. Her parents and especially the neighbors definitely disagree.
- Morality Pet: A literal example to Georgia, because she likes Angus and cares about her cat.
- Cannot Tell a Joke: Well known for his terrible jokes and sense of humor.
- Even the Guys Want Him: Invoked at least once, with other male teacher Herr Kamyer being attracted to him, like all the girls.
- Hot Teacher: All his students, and apparently some teachers, find him gorgeous.
Ms. "Hawkeye" Heaton
- Death Glare: Usually towards Georgia and her friends. She gives them a murderous look when they are acting silly.
- Hero Antagonist: To Georgia and all her shenanigans. She's just a teacher who is doing her job, even if Georgia sees her as an antagonist.
- Stern Teacher: She comes off as this, though Georgia sees her as a Sadist Teacher. She can see "rule-breaking" from a mile away and is always suspicious of Georgia.
- Butt-Monkey: One of Georgia's favorite targets to pick on, among the teachers. He seems oblivious to it though, even when Georgia and her friends tried to make him fall in the river.
- Funny Foreigner: As Georgia says "He has the double comedic value of being both German and the only male teacher in an all girls school."
- Butch Lesbian: A masculine PE teacher who's known to be lesbian. Initially the lesbian part was just an Informed Attribute, then it becomes sort of a Running Gag.
- Sadist Teacher: One of her nicknames is "Adolfa". Georgia even mentions she has a moustache.
- Butt-Monkey: Obviously thanks to Georgia and her friends's antics. She can't control the class and the students take advantage of this to make fun of her.
Ms. "Slim" Simpson
- Dean Bitterman: The stern headmistress of Georgia's school.
- Fat Bastard: Georgia always says she's fat. She's also very strict and often scolds the students. She is more stern than bastard, however.
- Ironic Nickname: "Slim" obviously, because she's extremely overweight.
- Large and in Charge: "Our large and glorious leader", as once Georgia said.
Mr. "Elvis" Attwood
- Butt-Monkey: Georgia loves to mess with him and play pranks on him. After a particularly bad prank, he trips on his wheelbarrow and ends up in hospital.
- Grumpy Old Man: He's cranky and unpleasant, though he has a good reason to dislike Georgia and her friends.
- Academic Alpha Bitch: In the books. She's made prefect and later Head Girl at school, and she uses her power to torment Georgia.
- Academic Athlete: Other than being smart, the Head Girl and kind of a Teacher's Pet, she also plays tennis and hockey, and she's apparently good at them (second only to Georgia, obviously).
- Alpha Bitch: Played straight in the movie. In the books it's either her or Georgia herself, depending on your view (though both of them have shades of this, Georgia has her redeeming qualities, while Lindsay is just an antagonist).
- Clingy Jealous Girl: When her ex-boyfriend Robbie starts dating Georgia, she doesn't take it well. She's so clingy that she actually tries to hurt Georgia out of jeaolusy.
- Fake Boobs: Her bust is actually the result of her stuffing her bra, as Georgia discovers in the first book.
- The Rival: Georgia's rival for the affections of Robbie and Masimo.
- Romantic False Lead: This. Lindsay was pretty much there to be Georgia's romantic rival. Georgia likes Robbie, but he's dating Lindsay. Georgia likes Masimo, but he's dating Lindsay. Obviously both guys end up dumping Lindsay and becoming Georgia's serious love interests, But it's eventually subverted since Georgia chooses Dave at the end, her Third-Option Love Interest.
- Yandere: A borderline example. After Robbie breaks up with her, Lindsay intentionally hurts Georgia during a hockey game, and injures Georgia's ankle.
"Nauseating" Pamela (P.) Green
- Butt-Monkey: An unpopular, nerdy girl who is often picked on.
- Stalker Without a Crush: To Georgia, after the latter saves her from the Bummer twins. She starts following Georgia everywhere, to the annoyance of the latter.
The Bummer Twins (Jackie Mathews and Alison Peters)
- Demoted to Extra: In the books, they're the school bullies and act on their own. In the movie, they get much less to do, and are just Lindsay's Girl Posse.
- Gang of Bullies: More like a duo, but they terrorize the other students.
- Laser-Guided Karma: When they frame two other students for shoplifting, Georgia decides to tell Slim the truth and the Bummers are immediately suspended.
- Put on a Bus: After they are suspended, they are not even mentioned again.
- Related in the Adaptation: In the book, they're not twins at all (or sisters, for that matter), it's just Georgia's nickname for them. In the movie they are literally identical twins.
- Single-Minded Twins: In the movie version, they're twins that look and act exactly the same.
- Those Two Bad Guys: Those two bad girls, actually. They are the token school bullies who are almost always mentioned together.
