This is a characters list of Japanese manga and anime series Crayon Shin-chan created by Yoshito Usui.

Main characters (野原 信之介)

A five-year-old boy in kindergarten and a member of Kasukabe Defence Force. He is Hiroshi and Misae's son and Himawari's brother and is nicknamed "Shin-chan". His favorite things are chocolate biscuits and the characters "Action Kamen" and "Kantum Robot", while he dislikes green bell peppers. Like his mother, he is gluttonous, stubborn, forgetful and prone to imagining things, and, like his father, likes to read adult magazines and flirt with young girls, especially if they are dressed in revealing clothing. Unlike his parents, he is shameless, outspoken and often insensitive towards others and infatuated with humor related to the buttocks, which makes them uncomfortable. Due to his age, he cannot read, write, or speak properly, so he often misreads and mispronounces words. He often indulges in age-inappropriate jokes, mostly scatological jokes and pulling down his pants to reveal his buttocks and/or genitals and dancing in the process. He also loves to indulge in drag. Despite his crude nature and destructive behavior, he genuinely loves his family and shows instances of selfless kindness and maturity beyond his years, such as saving a frog from a truck despite it ruining his last set of clean clothes and giving Masao his change despite knowing that Misae will scold him later. He is known as Shin-chan Nohara in the Vitello, Phuuz, and Indian dubs, and Shin Nohara in the Funimation dub. Julian Ryall of the South China Morning Post referred to him as the "Japanese Bart Simpson".

Misae Nohara

Shinnosuke's mother, who is from Aso in the Kumamoto prefecture of Kyushu. While she is caring and nurturing, her positive aspects are overshadowed by her flaws. She often does not follow the rules she sets for her family and is frugal, but willing to splurge on Himawari and herself; however, most of these purchases end up broken or misused. She also secretly hoards money for personal use, which often ends up being spent on running the household in times of financial strain. Since she has issues with maintaining her appearance, she is jealous of Hiroshi interacting with others. Due to her inability to use computers or speak English, Misae is unable to seek office work, so she occasionally works part-time at the local shopping mall, but is unable to keep the job for long due to her short temper. While living at Falling Apartments, Misae is shown to have worked part-time from home. She is known as Mitsy Nohara in the Vitello, Phuuz and Indian dubs and Mitzi Nohara in the Funimation dub and the One Peace English manga.

Hiroshi Nohara

Shinnosuke's father, who is from a village near Omagari in the Akita prefecture of northern Honshu and is a graduate of Waseda University. He is his family's sole source of income, working as a low-level manager at the marketing firm "Futaba Corporation" in Kasumigaseki, but allows Misae to handle the family's spending. He is a stereotypical Japanese salaryman, working eight-hour days and frequently working overtime, and giving all of his take-home pay to his wife each month. While his relationship with his family is positive, he and Misae often argue over issues such as Misae's frugal nature and the allowance she gives him to spend on his personal needs. She dislikes his passion for golf, seeing it as a waste of time, although he sees it as a way to bond with his boss. Although he wants to save his allowance for things he wants, usually new golf clubs, Misae often takes it to spend on shopping sprees. He is known as Harry Nohara in the Vitello, Phuuz, and Indian dubs, and Hiro Nohara in the Funimation dub.

Himawari Nohara

Shinnosuke's sister and the youngest child of the Nohara family, whose name, which means "sunflower" in Japanese, was chosen by the show's viewers rather than the creator. She is an energetic and precocious, and despite her young age, has matured and become more intelligent over the course of the series. Her parents hoped that she would be different from her brother, but to their dismay, she shares his mischievous nature. She looks up to her brother a lot and is very close to him despite their sibling rivalry. She is known as Daisy Nohara in the Vitello and Phuuz dubs and Hima Nohara in the Funimation dub.

Shiro

is a white Maltese puppy who Shinnosuke found and adopted after finding him abandoned in a cardboard box by the side of the road. He is intelligent, often displaying logic and intellect that surpasses that of his owners. Although he is a beloved member of the family, he is often the victim of neglect, as he is infrequently fed and has developed a talent for foraging. As well, they often do not realize his help or what he is trying to show them. He is very protective of Himawari. He is known as Lucky in the Vitello and Phuuz dubs and Whitey in the LUK International dub and Funimation dub; in the latter, he has an added British voice over and it is mentioned that he had a brother named Blackey, who was also found and taken in by Shinnosuke's family, but died after being hit by a car.

Toru Kazama

Shinnosuke's friend, who is close to him despite their frequent fights and secretly recognizes him as his best friend, despite denying it publicly. He attends cram school for Mathematics & English Conversation and participates in many extra-curricular activities in the aim of being admitted to a reputed primary school, so he pretends to be knowledgeable in subjects even if he is not. He is skilled at playing association football and baseball and likes animation and comic books, though he tries to hide this from his friends in order to appear more mature. Since his father remains abroad for most of the year, he has a strong attachment to his mother, which he is often ridiculed for. He often he tries to hang out with upper class girls his age from his cram school to be a part of the "elite". Although Kazama is sometimes suggested to look down upon Shinnosuke due to the economic status of his family and his weird mannerisms, he is secretly envious of him for having a younger sister and a pet dog. He is known as Cosmo in the Vitello and Phuuz dubs and Georgie Herbert Walker Prescott III in the Funimation dub, where he and his family are portrayed as being Republicans.

A five-year-old girl who is Shinnosuke's classmate and only female member of the Kasukabe Defence Force. Like her mother, she uses a stuffed bunny as a punching bag to relieve her anger, yet likes rabbits. She considers Ai-chan her rival, bickering with her for influence among the boys. She loves to play 'real omamagoto', or 'real house', which is a re-enactment of Japanese dramas that she usually forces her friends to play over other games. Despite this and her headstrong nature, she is kind and loves her friends and will not hesitate to stand up for them. She is known as Nini in the Vitello and Phuuz dubs and Penny Milfer in the Funimation dub. In the LUK Internacional dub, she has a British accent.

A five-year-old boy who is shy and cowardly and has low self-esteem, which he is often teased for; despite this, Nene encourages him to stand up for himself.

He is in love with Ai and jealous of Shinnosuke because of her love for him, but despite this they are still best friends. He is known as Max in the Vitello and Phuuz dubs and Maso Sato in the Funimation dub and in one chapter of the One Peace manga. The Funimation website says that Maso is like "Linus without his blanket.""Official Shin-chan website." Funimation. Retrieved on September 30, 2009.

A five-year-old boy and Nisu's brother, who is one of Shinnosuke's best friends. He is smart despite his slow and stoic nature, which often surprises his friends. He enjoys collecting stones and investigating urban legends, such as UFOs. He is known as Boo in the Funimation dub. The Funimation website says that Boo is "sort of like Dim from A Clockwork Orange, or Eeyore from Winnie the Pooh,- without the depression." In the Hindi dub he was called Suzuki in the earlier dubs, but uses real names in the later dubs.
