David Rudman (2001-present)
- Anti-Role Model: He eats terrible, unhealthy food nonstop, and he's proud of it.

- Big Eater: He can and will eat just about anything.
- Big Word Shout: Less frequently, he will shout "Cowabunga."
- Characterization Marches On: He behaved more like a toddler in the first season: he often interfered with others (though unaware he was doing so), was occasionally fussy when he didn't get his way and was scolded by other characters when he misbehaved. It wasn't until his song "C is for Cookie" in 1971 that Cookie Monster's personality was firmly established.
- Catch Phrase: "COOOOOKIE!" and "OM-NOM-NOM-NOM!"
- Crazy Consumption: Usually found eating very quickly while eating cookies.
- Deadpan Snarker: Surprisingly. It's sometimes hard to tell with his Hulk Speak, but he can be quite sarcastic - complete with Aside Glances, even.

"That taste even better than Latin Grammy!"

- Foregone Conclusion: Cookie Monster will eat any cookies that are near him, no matter how important they are. He's gotten better, though.
- Hidden Depths: He tends to come off as a dim-witted glutton, but as the years went by he started to be portrayed less dense and more single-minded. He's can be very clever when he wants to be, is a surprisingly talented artist (if he can resist eating his own paintings), has shown himself to be a big fan of high culture (host of "Monsterpiece Theatre" as the gentrified Allister Cookie), and even got a few Deadpan Snarker traits over time.

- Leitmotif: A short, instrumental version of "C Is for Cookie."
- More Teeth than the Osmond Family: In his earliest appearances, he had fangs.
- Only Known by Their Nickname: According to the song "The First Time Me Eat Cookie", his name was Sidney before he started eating cookies - the "Cookie Monster appellation was just a nickname that stuck.
- Parental Bonus: The undisputed king of this trope. If Sesame Street makes a clever pop-culture reference, chances are it comes from him.

- You No Take Candle: His well-known speech pattern is his bad grammar.

Then, during Richard Hunt's stint, he was like a rowdy caveman (sounded a lot like Two-Headed Monster).

- No Name Given: He was a minor background Muppet simply known as "Baby Monster" before 1985, when his current character started to take shape.

- Unsatisfiable Customer: When he was at Charlie's, Simon ranted, "Why did my brother recommend this restaurant? The service is terrible." It may be that Simon Soundman's brother is the usual customer, Mr. Johnson. And both are Fat Blue Anything Muppets originally performed by Jerry Nelson.
- Jim Henson
- Men Are Tough: Well, Sam looked for some suspect for some problems he is having problem. Like at one time, he was looking for Doc Holiday because he had an itchy trigger finger (and he means his finger is really itchy).

- One-Shot Character: He never appeared outside the Miami Mice skits (only 3).

- Fairy Tale Motifs: She is a textbook example of a fairy. Well... okay, aside from being a little fuzzy.
- Girly Girl with a Tomboy Streak: In "Dress-Up Club", she wants to dress up like a superhero and a pirate. Hilarity Ensues (It Makes Sense in Context).
- Punny Name: It's a play on the stereotypical "magic word" Abracadabra.
- Mundane Object Amazement
- Mundane Utility: In addition to transforming one thing into something completely different or conjuring things out of thin air, her wand also makes a handy backscratcher.
- Non-Standard Character Design: She, along with other fairy characters in the show, is one of the few Muppet characters designed with irises. To quote the Muppet Wiki:"Abby's design is an intentional departure from the typical Muppet look because she's not originally from Sesame Street. The implication is that the fairies in her old neighborhood look like her."
- Pink Means Feminine: Her fur is bubblegum pink.
- Rhymes on a Dime: Abby does rhymes whenever casting spells.
- Shoe Phone: The secondary use for her wand is to substitute for a cell phone.
- Signature Laugh: A cute little giggle.
- Wide-Eyed Idealist: Many small children see their world as a place of tremendous beauty and endless possibilities. Abby is no different.

- Literary Agent Hypothesis: He's the bear from the Goldilocks story.
- Sure, Let's Go with That: He unwittingly names his sister when he meets her.

Brian Muehl (1978-1984)
Fred Garver (1984-1993)
Bruce Connelly (1993-present)
- Big, Friendly Dog: A big, playful dog.
- Hidden Eyes: His eyes are covered by his hair.

- Tempting Fate: On several occasions, Bert ends up on the receiving end of Ernie's craziness simply by pointing it out.
- Caroll Spinney (1969-present)
Daniel Seagren (understudy in a handful of episodes dating to 1970)
Matt Vogel (understudy, 1998-present over roughly 20 episodes)
- A Dog Named "Dog": He sure is a large aviary creature. Hey, what's this guy's name again?
- Breakout Character: Is the star of the first official Sesame Street movie Follow That Bird, starred in specials where he travels to China and Japan and is the star of other merchandise items such as storybooks, cassette tapes or records. Possibly the first breakout character before Elmo.
- Cassandra Truth: The adults constantly disbelieved Snuffleupagus was real at first. See The Reveal under ''Mr. Snuffleupagus"
- Characterization Marches On: He was initally a fully grown idiot with a hick-like Simpleton Voice to match rather than the innocent Man Child he eventually became.
- The Cutie: Even in the context of Sesame Street his innocence and sweetness stand out.
- Extreme Doormat: Well, maybe not "extreme", but he has a hard time standing up for himself - he once let Humphrey and Ingrid talk him into giving Radar to Natasha, and he would have lost his nest to Minnie Myna if Chris hadn't helped him.
- Gentle Giant: He's a Big Bird with a good heart.
- Hidden Depths: During the famous episode centered on the death of Mr. Hooper, Big Bird draws various caricatures of the adults - of a quality that you may not normally see from a typical 6-year-old.
- Caroll Spinney is a cartoonist and painter in his down time, overlapping with The Cast Showoff.
- Meaningful Echo:Gordon: Why are you walking that way?
Big Bird: "Just because."
(Big Bird learns of Mr. Hooper's death)
Big Bird: "Why does it have to be this way?"
Gordon: "Big Bird, it has to be this way because."
Big Bird: "Just because?"
Gordon: "Just because."
- Start My Own: Because Oscar wouldn't let him join the Grouchketeers.
- Trademark Favorite Food: Birdseed, which he eats (or in the case of birdseed milkshakes, drinks) in seemingly infinite variations.
- Vocal Evolution: Big Bird started off as a fully-grown Village Idiot with a deep, hick-like voice. Over time, however, he became a young child of 5 (or 6, depending on when you were watching the show) with a higher-pitched voice. Because the show reuses its old recordings of songs in later episodes, it can be very jarring to hear Big Bird sing the "Alphabet Song" in his "hick" voice in an episode from c.1975 or later.
- Rick Lyon
- One-Shot Character: He only appeared in 2 sketches.
- Richard Hunt
- That Makes Me Mad: Well, Bert got angry with Ernie about putting too many toys in the tub.
- Carroll Spinney
- Suddenly Voiced: All though Bruno is usually a silent character, He did speak a few times (like in the end of Follow that Bird, He replied to Oscar "Sure, Boss!"). He even sang with The Trashmen with the song, "Put it in the trashcan".
- Richard Hunt

- Joseph Mazarrio
Davey and Joey Monkey
- David Rudman (Davey Monkey)
Joseph Mazarrio (Joey Monkey)
- Jim Henson (1969-1990)
Steve Whitmire (1990-2014)
Billy Barkhurst (2014-present)
- Consulting Mister Puppet: Ernie often talks to his trademark rubber duckie about his problems.
- Couldn't Find a Pen: Bert asks him to make a shopping list, and the only thing Ernie can find to write with is chocolate pudding. Ernie then makes a list of all the writing implements that he couldn't find. Ernie tacks chocolate pudding onto the end of the list, since he needed to use all the pudding in the apartment to write it out.Bert: "He's improving. Last time he used spaghetti sauce."
- The Gadfly: He loves to prank, trick and tease Bert. Much of his random weird behavior is just done to mess with his friend, because it's funny when Bert gets frustrated.
- Hidden Depths: He lays down an amazing saxophone solo during "Put Down the Duckie."
- He's also a really good painter... even if he does re-imagine Bert as a beatnik.
- I Can't Hear You: "I can't hear you, Bert. I have a banana in my ear."
- Jerk with a Heart of Gold: Well, yeah — you wouldn't think so, but Ernie is a far bigger jerk than Bert. Watching the Bert & Ernie skits, it's sometimes surprising to see just how badly Ernie treats his best friend, often for no good reason at all. He plays tricks on him, makes a fool out of him, steals his snacks or cruelly tempts Bert with snacks before eating them himself, and in general causing him no end of frustration, humiliation and heartache. When Ernie still comes across as the most likeable and friendly of the two, it's because, well, he is a genuinely sunny and affable person who just wants to have fun and share a laugh with people. He's never malicious, just a little insensitive.
- The Prankster: Usually pranks Bert.
- Pungeon Master: This was an especially pronounced trait of his in the first season.
- A good example would be his very first appearance, when he tells Bert he calls the bathtub "Rosie", and when Bert asks why he replies, "Because every time I take a bath, I leave a ring around Rosie."
- Security Blanket: His rubber ducky.
- Signature Laugh: "Kshshshshshshshsh!"
- Signature Song: Rubber Ducky, You're the one! You make bathtime lots of fun...
- Something Only They Would Say: The game "Journey to Ernie" runs on this trope.
- Straight Man: He's sometimes used as this, as when he's paired with Cookie Monster.
Fine Young Camels
Paul Jacobs (Lead Singer/Voice Only)A Muppet Camel with two Anything Muppet Arabian guys (One Lavender and one Tall Orange) as back up singers. They sang C Drives Me Crazy.
- Richard Hunt (1986-1992)
David Rudman (1992-1993)
- No Celebrities Were Harmed: She is based on the French writer Gustave Flaubert.
- Carroll Spinney
- Cool Old Guy: A kindly old bird.
GrouchesA group of crusty, monster-like creatures indigenous to Grouchland.
- Big Ol' Unibrow: As mentioned under Oscar's entry, it's a species trait.
- Bizarro Universe: Grouch society mirrors human society (right down to similar celebrities — Dan Rather-Not and Donald Grump, for example), but they prefer unhappiness and filth to happiness and cleanliness.
- Blue and Orange Morality: As explained above, they dislike (often downright condemn) nice and pleasant things, and like things that most other people would find unpleasant. Although a bit odd, it sounds simple enough, right? Well, this also means that they like feeling miserable, and yet the nice things they hate make them miserable, which they like and... yeah. Try not to think about it too hard.
Honkers & Dingers
- Gag Nose: Honkers squeeze theirs in order to honk.
- The Unintelligible: They only speak in honking and dinging.
- Shout-Out: The Honkers are essentially an entire species of Harpo Marxes.

- The Speechless: Although they do not speak, Their performers will vary depending on what puppeteer is available.
Hoots the Owl
- Kevin Clash (1985-2001, 2005)
- Destined Bystander: He (or, at least, the puppet that would later come to be him) first appeared in a single scene in Sesame Street Presents: Follow That Bird.
- The Owl-Knowing One: Not all-knowing, but he's wise enough to know you can't play the sax with a rubber duck in your hand, and that carrots are healthier than cookies.
- Frank Oz (1976)
Jerry Nelson (1992)
- No Celebrities Were Harmed: Well, he is based on the famous nursery rhyme: Humpty Dumpty sat on the wall, Humpty Dumpty had a great fall....
- Jerry Nelson
- No Celebrities Were Harmed: He is based the late radio announcer Wolfman Jack.
- Stacey Gordon (2017-present)
- Character Tic: Flapping her arms in excitement.
- Cloudcuckoolander: Described as doing things "in a Julia sort of way".
- Hollywood Autism: Subverted; Julia's portrayer, Stacey Gordon, has a son who is autistic.
- Inspirationally Disadvantaged: As storylines progress about Julia, her strengths were set to be played up. In her first appearance, for instance, she is participating in a game when she begins jumping up and down. Instead of rejecting Julia, the other characters and Muppets decide that jumping up and down is a lot more fun.
- Non-Standard Character Design: The show's puppets typically only have one articulated arm, but she has both due to the above-mentioned Character Tic.
- The Quiet One: Doesn't talk much.
- Security Blanket: Her raggedy toy rabbit, which is torn in several places and perhaps looks like it should have been thrown out years ago. But it is her comfort object.
Kermit the Frog
- Jim Henson (1955-1990 [the character predates Sesame Street])
Steve Whitmire (1990-present)
- Beware the Nice Ones: Kermit is usually friendly and even-tempered, but when he's pushed too far he can get very angry indeed.
- Butt Monkey: Frequently the victim of Grover's bumbling and Cookie Monster's hedonism, among other misfortunes, almost to the point of being The Chew Toy.
- Catch Phrase: "Heigh-ho, Kermit theee Frog here at Sesame Street News..."
- Phrase Catcher: Grover's "HEYYYYY, FROGGY BAYBEEEEE!" backslap-greeting.
- Call Back: He makes a surprise appearance in "Elmo's World: Frogs", where he is shown lounging in his apartment.
- Continuity Nod: While preparing to interview Old MacDonald, Kermit tells one of the farmer's pigs, "You know, you remind me of somebody..." (a reference to The Muppet Show's Miss Piggy).
- Crossover: Kermit once made routine guest appearances, frequently playing off Grover and Cookie Monster. Alas, the frog seldom appears these days, due mainly to Disney owning the rights to the character.
- "I Am" Song: "Bein' Green" and "This Frog".
- If You Can Read This: An actual cameraman is named on the slate in the Oklahoma! sketch.
- Intrepid Reporter: During the "Sesame Street News Flash" segments.
- Is This Thing Still On?: A running gag in the news segments.
- Loud Gulp: The idea of a frog eating a fly makes him nauseous.
- Somewhere, a Herpetologist Is Crying: This is Zigzagged in one scene, in which Bob lists frog facts, and Kermit insists that frogs act more like people, with human diets and apartment buildings.
Lil' Fish Dude
- Steve Whitmire
- One-Shot Character: He only appeared in Love the Ocean.
- Fran Brill
- Fish out of Water: In their first few years they were very unfamiliar with Earth, to the point where they spent most of their time attempting to communicate with inanimate objects.
- Incredibly Lame Fun: They dance to radio static.
- Innocent Aliens: They're just confused tourists.
- Intangible Man: They often enter scenes by phasing through walls.
- Special Person, Normal Name: The primary two are named "Joe" and "Bob." Although in the game show sketch Bring that Thing, Guy Smiley addressed them as "Stevie" and "Jonathan" Martians.
- Jerry Nelson
The Oinker Sisters
- Special Person, Normal Name: One of the Oinker Sisters is named "Suie Oinker".
Oscar the Grouch
- Caroll Spinney (1969-present)Eric Jacobson (understudy,2014-present)
- Anti-Role Model: One purpose of the character is to poke fun at irritable people. Which isn't to say that his irritation isn't justified sometimes.
- Big Ol' Unibrow: Huge eyebrows are a species trait.
- Bizarre Taste in Food: He hates foods most would consider nice or healthy, but loves noxious combinations of food that are technically still edible... just really gross. Like sardine ice-cream. Again, it's a species trait.
- Early Installment Weirdness: He was orange for a year. (Apparently he still would be, if he ever bathed.)
- Grumpy Bear: He's a Grouch. It's a species trait.
- Hoist by His Own Petard: Every now and then, some of the mean-spirited pranks and schemes he pulls tend to backfire, where he may end up being the victim himself. Often happens when he's frustrated when targeting a rather slow-witted character with his pranks.
- Jerkass: Cranky, rude, and mean. Although as much is allowable on a preschool show. The Muppet Wiki puts it best:Oscar's mission in life is to be as miserable and grouchy as possible, and pass that feeling on to everyone else. When a visitor knocks on his trash can — invariably interrupting him from a nap or an important task — Oscar greets them with a snarl. He complains that he wants to be left alone, although when he's left entirely to himself, he's dissatisfied — there isn't anybody around to irritate or complain to.
- Jerk with a Heart of Gold: The true depths of his jerk nature are often called into question and he can get comically defensive when his reputation as a "true Grouch" is threatened.
- Nice Job Fixing It, Villain!: There does appear to be an occasional running gag, where as mentioned previously when his intended mean-spirited ways backfire, unwittingly causing rather pleasant and helpful results for other characters along with a few other schemes he may try to pull. Much to his dismay, of course.
- The Nicknamer: As far as Oscar is concerned, Bob and Maria are Bright Eyes and Skinny, respectively.
- The Pigpen: Always seen in a trash can, so yeah.
- Slap-Slap-Kiss: His relationship with Grungetta.
- Slave to PR: One has to wonder if he'd be so concerned about being a "real Grouch" - or if he'd be so self-conscious anytime he says, does, or thinks something even remotely pleasant - if it weren't for Grouch society constantly stressing how Grouches are supposed to act.
- Too Important to Walk: He's rarely seen walking. When he needs to be transported somewhere, a garbageman named Bruno carries his can. (He does in Christmas Eve on Sesame Street a few times.)
- Troll: He can definitely come off as this at numerous times.
- Vitriolic Best Buds: Easily with any of the nice Sesame Street residents that like being sweet and chummy with him, especially Elmo, Telly, and Maria.
- With Friends Like These...: Used to be this sort of "friend" to poor Telly.
- Although, they seem to have fallen into a more traditional Type 1 Vitriolic Best Buds as of late.
- Your Approval Fills Me with Shame: Often inverted. As you may expect, he does not appreciate being praised by the other characters for doing something less-than-grouchy.

Richard Hunt (1971-1975)
Peter Friedman (1976-1978)
Brian Muehl (1979)
Frank Kane (1979)
Bryant Young (1979-present)
- Abandoned Catchphrase: Mr. Snuffleupagus used to always say "Oh, dear" in a worried voice. Big Bird even lampshaded it once; when Snuffy went missing in one episode and BB called the police (an Anything Muppet) to take a report, part of his description was that he said "Oh dear" a lot.
- Characterization Marches On: He started out with a rather odd and perpetually sad personality as well as speaking with a rather creepy, echoing, sad voice. It wasn't until when Marty Robinson took over the character that, though still sad occasionally, his personality became relatively more cheerful and his voice had a wider range of emotions.
- Early Installment Weirdness: Snuffle used to have wide yellow eyes with green sclera and was understandably changed to a different lazy eyed design as the debut appearance was... unsettling, to say the least.
- The Eeyore: Used to be one of his defining character traits, but he steadily grew out of it as time went on.
- In-Series Nickname: "Snuffy." He calls Big Bird "Bird."
- Missed Him by That Much: In his early appearances, he'd wander off before anyone other than Big Bird could spot him, leading to speculation that he was BB's Imaginary Friend.
- Not-So-Imaginary Friend: For Big Bird. Everyone assumes that Snuffy is imaginary and even Big Bird thinks this at one point, but they are convinced otherwise later on.
- Only Known by Their Nickname: His real name is Aloysius Snuffleupagus. Even though almost everyone on the series refers to him by his nickname, his mother usually refers to him by his real name.
- Precocious Crush: Pre-dating the Elmo and Gina plot (see above), he had such a crush on Maria for a while.
- Real After All: He is revealed to the adult cast 13 years after his debut, in order to encourage kids to be more honest with their parents. It was an emotional experience for the characters and actors.
- Steve Whitmire
- It Was a Gift: Well, he likes to deliver things to other characters. He once tried to give Elmo a sign that reads ABCDEFGHIJKLMNOPQRSTUVWXYZ. Elmo ended up singing the famous song originally sung by Big Bird. At that point, Big Bird and the kids told them that it's not a word, It's the alphabet.

- Bob McGrath (1969-present)
- Aerith and Bob: The literal "Bob" to his brother Minneapolis's Aerith.

- The Danza: Bob McGrath plays Bob Johnson.

- Running Gag: The production staff loves to put Bob in costumes.
- Will They or Won't They?: Bob and Linda dated, But they never were married.

- Carlo Alban (1993-1998)

- Christopher Lawrence Knowings (2007-present)

- Alliterative Name: His full name is Harold Hooper.
- Bus Crash: How he dies.
- Cool Old Guy: A snarky, funny guy.
- Death Is a Sad Thing: Played so, so straight with his death. In doing the episode's defining scene in one take, an unintentional lesson — that even adults cry and feel deeply saddened when someone they are close to dies, and that oftentimes entire families cry together in times of grief (indeed, several of the adult characters are visibly emotional and on the verge of tears as they explain to Big Bird that Mr. Hooper died and is not coming back ... ever) — made its indelible mark on this episode and earning it critical acclaim.
- Jerk with a Heart of Gold: Mr Hooper is somewhat sarcastic but he is a nice person.
- Last Name Basis: As the oldest on the street in his day, he considered this a mark of respect.
- Never Say "Die": A subversion, which is still met with acclaim today; after his actor died, the writer's decided to use the opportunity to directly address death for the show's young audience.
- Suddenly Ethnicity: Bob wishes him a Happy Hanukkah in Christmas Eve on Sesame Street.
- The Character Died with Him: He was killed off after his actor (Will Lee) died on December 7, 1982.
- They Call Me Mister Tibbs: Harold Hooper was seldom referred to by his first name. Two known instances among a handful: The episode when Hooper got his GED (sometime in the mid-1970s); and in 1980, when Maria took a job as a census taker and interviewed Hooper.
- Unexpected Successor: David had to pretty much scrap his plans for law school when Mr. Hooper died.

- Linda Bove (1972-2002)

- The Speechless: Linda never did speak because she is deaf.
- Will They or Won't They?: Bob and Linda dated, but they didn't get married.
The Number Painter
- Paul Benedict (1972)
- Hilarity Ensues: Most of the Painters' antics would get him arrested for such things as trespassing, vandalism and criminal mischief.
- Emilio Delgado (1971-present)
- Gratuitous Spanish: Not so much these days, now that Rosita's around.
Maria Rodriguez (née Figueroa)
