This is a list of all the characters in Sarah & Duck.
A seven-year-old girl who embarks on many weird and wonderful adventures with her best friend Duck.
- Childish Tooth Gap: When she smiles, you can see she has a few teeth missing, though it's justified as she's seven and kids usually lose their baby teeth at this age.
- Nice Hat: She is rarely seen without her signature green beanie hat, but when she dresses up, she will swap it for a hat that matches whatever costume she's wearing.
- In the episode where she celebrates her birthday, Scarf Lady gives her a really cute mouse hat.
- Trademark Favorite Food: Loves anything with lemons, especially lemon water and cherry tomatoes.
Sarah's best friend.
A friendly older woman who is a neighbor and friend of Sarah and Duck. She loves knitting and is rather absent-minded. Luckily, she has her trusty talking Bag to correct her at times.
- Cool Old Lady: Her knitting skills are phenomenal. She once knitted a huge hat for her "Weeping Woolen Tree," where she gets all her wool from (yes, wool grows on trees here), which took nearly her entire supply of yarn, which Sarah and Duck helped to resupply when she ran out.
- One episode reveals she competed in many winter sports during her youth, her favorite being bobsledding. Another episode sees her competing in an annual hot-air balloon race with her rival Hat Lady, using a balloon she knitted herself!
One of Sarah and Duck' friends, who is obsessed with plates.
An eccentric older man who looks after the local library, and is always on hand to help the other characters find the books they're looking for.
Another friend of Sarah's, who is usually accompanied with his best friend Flamingo.
- Facial Markings: Has spirals on his cheeks.
- Gratuitous Japanese: He is strongly implied to be of Japanese descent, since he lives in a Japanese-style bungalow, has a pet octopus named Tako and also says "Itadakimasu" (which Sarah adorably mispronounces as "It's a ducky mess") before he eats his meals.
- Spear Counterpart: To Sarah.
- Why Did It Have To Be Stairs?: Some episodes show he's scared of using stairs, so much so that Flamingo sometimes has to carry him up and down.
Two identical twin girls who are Sarah's next door neighbors. They are obsessed with ribbons and often use them for communication.
- Circus Brat: One episode reveals their family runs a circus that they perform in and often tours the world.
- Cool Shades: One twin wears lemon-shaped shades while the other wears tomato-shaped ones.
- Creepy Twins: Subverted, since they're pretty much as preschool-friendly as this trope can get, though their giggling, tendency to speak in whispers and the fact that they never take off their shades doesn't usually help.
- Known Only by Their Nickname: It's unclear whether Ribbon is their last name or if it's a nickname. It's thought to be the latter, as the Circus Episode reveals they have two older brothers known as the Hoop Twins.
Another friend of Sarah and Duck, who loves riding around on his scooter.
- Cool Helmet: Wears a rather snazzy helmet that he never takes off.
- Fantasy Helmet Enforcement: As mentioned above, he is never ever seen without his scooter helmet on. In fact, he's so safety conscious, he endorses and gifts reflective safety stickers, stops riding his scooter the one time he has an accident until Sarah helps him, and takes part in a soapbox derby race... by making a cart that looks like a caution cone, driving as slowly as he can, and using a parachute to fully brake when he's already stopped.
- Known Only by Their Nickname: Just like half this page.
The owner of the local bakery.
John's best friend and Duck's opposite.
The pet of Scarf Lady
A small ladybug who is often trying to avoid getting in the way of the other characters' exploits, due to his size.
- Bioluminescence Is Cool: He's capable of making the sports on his back glow.
- Accessory-Wearing Cartoon Animal: Has a pair of windows on his shell, which he looks through while he's inside.
Scarf Lady's Bag, whom Scarf Lady is never seen without.
- Deadpan Snarker: Often seen as this, since he has to frequently put up with Scarf Lady's absent-mindedness, as well as endlessly correcting her whenever she gets her words mixed up.
The Moon, who often comes down to Earth and is friends with Sarah and Duck.
A talking umbrella who lives with Sarah and Duck.
- Why Did It Have To Be Rain?: Despite what he is, he's terrified of rain.
A quartet of shallots, three large ones and a small one, who live in Sarah and Duck's garden.
- Plant Person: Played with, since they're a bunch of living vegetables.
- Nephewism: Reveals he has a niece in one episode, who appears to form a double rainbow.
The planet Venus, whom Moon has a crush on.
- Gentle Giant: She's a tad bigger than Moon, but is as friendly.
A talking living cake who came to be after one of Sarah and Duck's baking sessions. He now resides at the bakery with Bread Man.
- What the Hell Is That Accent?: Speaks with a rather French-sounding accent.
